Module lsp_helpers 

Shared LSP response builders.

Structs

CharOffsets

Maps a yaml-rust2 char index to a byte offset in content, and a byte offset to the end of its containing line.

DependencyOutcome

Everything the lifecycle fetch learned about one package, keyed by its normalized name.

DependencyOutcomes

Normalized-package-name -> DependencyOutcome map.

DiagnosticSeverities

Diagnostic severity levels for the four per-dependency issue categories.

LineOffsetTable

Converts byte offsets in source text to LSP Position values.

PackageVersions

Registry version data for one package, fetched together in a single round trip.

VersionData

Bundles the two per-package version maps (cached, resolved) that LSP handlers pass together everywhere.

Enums

RequirementStatus

Result of checking whether a dependency’s declared requirement is already satisfied by the latest known version.

Constants

CMD_DOT_FOOTER

The Cmd+. update-footer markdown this function appends when a code action may exist for the hovered dependency.

DEPRECATED_DIAGNOSTIC_CODE

Stable [Diagnostic::code] set on the package-level deprecation diagnostic (issue #205).

HOVER_RECENT_VERSIONS

Maximum number of recent versions hover’s “Recent versions” section renders.

MAX_FALLBACK_SCAN_BYTES

Upper bound, in bytes past search_from, on how far locate_value_span’s fallback scan will search.

UNSATISFIABLE_DIAGNOSTIC_CODE

Stable [Diagnostic::code] set on the unsatisfiable-requirement diagnostic.

Traits

DiagnosticMessages

Static wording for diagnostics and hover about yanked/deprecated package state.

DiagnosticPolicy

Per-ecosystem opt-outs for which diagnostics apply to which dependency/requirement shapes.

EcosystemFormatter

Umbrella marker for a complete ecosystem formatter.

OsvNaming

Native <-> OSV.dev namespace bridging for package names and version strings.

PackageNaming

Ecosystem-specific package name normalization and validation.

PackageRendering

How a package/version renders into manifest text edits and hover content.

RequirementMatcher

A requirement compiled by one ecosystem, ready to test candidate versions against.

RequirementResolution

Requirement parsing, matching, and up-to-date status.

SourcePolicy

What a DependencySource may be used for: resolution, vulnerability scanning, and cache-key/link trust.

Functions

collect_update_all_edits

Manifest edits bringing every safely-editable outdated dependency to latest.

compile_requirement_unless

Shared shape for a crate::lsp_helpers::RequirementResolution::compile_requirement guarded by one predicate.

concrete_pin_version

Returns the concrete version text requirement denotes, or None if requirement is not the shape of a single concrete version.

escape_markdown

Escapes Markdown syntax characters so untrusted text cannot break out of the Markdown structure it is embedded in.

generate_code_actions

Generates the code actions offered for the dependency at position.

generate_code_lenses

Zero or one lens for the document, bound to command_id.

generate_diagnostics_from_cache

Generates diagnostics using cached versions (no network calls).

generate_hover

generate_inlay_hints

in_use_version

The version of dep this project treats as actually in use.

is_dot_segment

Whether segment is exactly . or ...

is_full_semver_shape

Whether s has the shape of a full major.minor.patch version.

is_full_sha

Whether s is a 40-character hex string — a git commit SHA shape, shared by every ecosystem resolving refs against a git-tags-datasource API (GitHub, GitLab).

is_safe_maven_coordinate_segment

Whether segment is safe to embed as a Maven groupId/artifactId value in a pom.xml [TextEdit] or completion item.

is_safe_package_name

Whether name is safe to embed as a package name in a manifest [TextEdit] or completion item.

is_safe_registry_url

Whether url is safe to embed as a Swift Package Manager repository URL in a Package.swift [TextEdit] or completion item.

is_safe_version_string

Whether version is safe to embed in a manifest [TextEdit] or completion item.

is_same_major_minor

Checks if two version strings have the same major and minor version.

is_tag_shaped

Whether s has the shape of a tag ref: an optional leading v/V followed by a digit.

locate_value_span

Finds the byte offset in content (searching only within the line starting at search_from) where the literal bytes of value occur.

markdown_code_span

Wraps content in a Markdown inline code span (backticks included) that safely contains arbitrary untrusted text, regardless of embedded backticks.

match_v_prefix_style

Rewrites tag to match current’s leading v/V prefix style (or lack of one).

position_in_range

Checks whether a cursor position falls within an LSP range (inclusive on both ends).

requirement_is_unsatisfiable

Returns true when no published version satisfies requirement.

truncate_for_diagnostic

Truncates value to at most max_chars characters, appending … when truncated.

warn_rejected_value

Logs a tracing::warn! for a value rejected by an is_safe_* predicate (or an equivalent value-rejecting gate) before it reaches a manifest edit or registry URL.
