Enum DepsError 

pub enum DepsError {
    ParseError {
        file_type: String,
        source: Box<dyn Error + Send + Sync>,
    },
    RegistryError {
        package: String,
        source: Error,
    },
    CacheError(String),
    InvalidVersionReq(String),
    Io(Error),
    Json(Error),
    UnsupportedEcosystem(String),
    AmbiguousEcosystem(String),
    InvalidUri(String),
}

Core error types for deps-lsp.

Extended from Phase 1 to support multiple ecosystems (Cargo, npm, PyPI). All errors provide structured error handling with source error tracking.

Examples

use deps_core::error::{DepsError, Result};

fn parse_file(content: &str, file_type: &str) -> Result<()> {
    // Parsing errors are automatically wrapped
    if content.is_empty() {
        return Err(DepsError::ParseError {
            file_type: file_type.into(),
            source: Box::new(std::io::Error::new(
                std::io::ErrorKind::InvalidData,
                "empty content"
            )),
        });
    }
    Ok(())
}

Trait Implementations

impl Debug for DepsError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for DepsError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for DepsError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for DepsError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for DepsError

fn from(source: Error) -> Self
