Struct CliError 

pub struct CliError {
    pub category: ErrorCategory,
    pub source: Error,
}

A CLI error with a semantic category for exit code mapping.

Wraps an anyhow::Error with an ErrorCategory to enable proper exit codes while preserving full error context and chains.

Creating Categorized Errors

use blz_cli::error::{CliError, ErrorCategory};
use anyhow::anyhow;

// Explicit category
let err = CliError::new(
    ErrorCategory::NotFound,
    anyhow!("Source 'react' not found"),
);

// Using convenience constructors
let err = CliError::not_found("Source 'react' not found");
let err = CliError::usage("Invalid flag combination");

Fields

category: ErrorCategory

The semantic category of this error.

source: Error

The underlying error with full context.

Implementations

impl CliError

pub fn new(category: ErrorCategory, source: impl Into<Error>) -> Self

Create a new CLI error with explicit category.

pub fn inferred(source: impl Into<Error>) -> Self

Create a CLI error, inferring the category from the error message.

pub fn internal(source: impl Into<Error>) -> Self

Create an internal error.

pub fn usage(source: impl Into<Error>) -> Self

Create a usage error.

pub fn not_found(source: impl Into<Error>) -> Self

Create a not-found error.

pub fn invalid_query(source: impl Into<Error>) -> Self

Create an invalid-query error.

pub fn network(source: impl Into<Error>) -> Self

Create a network error.

pub fn timeout(source: impl Into<Error>) -> Self

Create a timeout error.

pub fn integrity(source: impl Into<Error>) -> Self

Create an integrity error.

pub const fn exit_code(&self) -> u8

Get the exit code for this error.

pub fn as_exit_code(&self) -> ExitCode

Create an ExitCode from this error.

Trait Implementations

impl Debug for CliError

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

Formats the value using the given formatter.

impl Display for CliError

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

Formats the value using the given formatter.

impl Error for CliError

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.
