Enum CodingError 

pub enum CodingError {
    File(FileError),
    Bash(BashError),
    Grep(GrepError),
    AstGrep(AstGrepError),

    NotConfigured(String),
}

Error types for all coding tool operations.

CodingError is the top-level enum returned by CodingTools methods and the tools exposed by CodingMcp. Each variant wraps a more specific error type.

Variants

• File – File read, write, or edit failures (FileError).
• Bash – Shell command execution failures (BashError).
• Grep – Regex search failures (GrepError).
• AstGrep – Structural AST search failures (AstGrepError).
• Find – Glob-based file discovery failures (FindError).
• ListFiles – Directory listing failures (ListFilesError).
• WebFetch – URL fetch failures (WebFetchError).
• WebSearch – Web search API failures (WebSearchError).
• NotConfigured – A tool was called that requires configuration not present (e.g. web search without a Brave API key).

Sub-error types

• FileError – NotFound, ReadFailed, WriteFailed, CreateDirFailed, InvalidOffset, PatternNotFound, Io.
• BashError – Forbidden, TimeoutTooLarge, SpawnFailed, InvalidRegex, JoinFailed, ShellNotFound, WaitFailed.
• GlobError – InvalidPattern, BuildFailed (shared by the search tools).
• GrepError – Glob, InvalidRegex, SearchFailed, PathNotFound.
• AstGrepError – PathNotFound, Glob, UnsupportedLanguage, InvalidPattern, ReadFailed, SearchFailed.
• FindError – PathNotFound, InvalidGlobPattern, LockFailed.
• ListFilesError – ReadDirFailed, ReadEntryFailed, MetadataFailed.
• WebFetchError – InvalidUrl, RequestFailed, Timeout, ResponseTooLarge, ParseFailed.
• WebSearchError – InvalidQuery, ApiError, RateLimited, Timeout, ConfigError, ParseError.

Trait Implementations

impl Debug for CodingError

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

Formats the value using the given formatter.

impl Display for CodingError

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

Formats the value using the given formatter.

impl Error for CodingError

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.
