Enum wax::GlobError

pub enum GlobError {
    Build(BuildError),
    Walk(WalkError),
}

General errors concerning Programs.

This is the most general error and each of its variants exposes a particular error type that describes the details of its associated error condition. This error is not used in any Wax APIs directly, but can be used to encapsulate the more specific errors that are.

Examples

To encapsulate different errors in the Wax API behind a function, convert them into a GlobError via ?.

use std::path::PathBuf;
use wax::{Glob, GlobError};

fn read_all(directory: impl Into<PathBuf>) -> Result<Vec<u8>, GlobError> {
    let mut data = Vec::new();
    let glob = Glob::new("**/*.data.bin")?;
    for entry in glob.walk(directory) {
        let entry = entry?;
        // ...
    }
    Ok(data)
}

Variants

Build(BuildError)

Walk(WalkError)

Available on crate feature walk only.

Trait Implementations

impl Debug for GlobError

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

Formats the value using the given formatter.

impl Diagnostic for GlobError

fn code(&self) -> Option<Box<dyn Display + '_>>

Unique diagnostic code that can be used to look up more information about this Diagnostic. Ideally also globally unique, and documented in the toplevel crate’s documentation for easy searching. Rust path format (foo::bar::baz) is recommended, but more classic codes like E0123 or enums will work just fine.

fn help(&self) -> Option<Box<dyn Display + '_>>

Additional help text related to this Diagnostic. Do you have any advice for the poor soul who’s just run into this issue?

fn severity(&self) -> Option<Severity>

Diagnostic severity. This may be used by ReportHandlers to change the display format of this diagnostic.

fn labels(&self) -> Option<Box<dyn Iterator<Item = LabeledSpan> + '_>>

Labels to apply to this Diagnostic’s [Diagnostic::source_code]

fn source_code(&self) -> Option<&dyn SourceCode>

Source code to apply this Diagnostic’s [Diagnostic::labels] to.

fn related(&self) -> Option<Box<dyn Iterator<Item = &dyn Diagnostic> + '_>>

Additional related Diagnostics.

fn url(&self) -> Option<Box<dyn Display + '_>>

URL to visit for a more detailed explanation/help about this Diagnostic.

fn diagnostic_source(&self) -> Option<&dyn Diagnostic>

The cause of the error.

impl Display for GlobError

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

Formats the value using the given formatter.

impl Error for GlobError

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

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<BuildError> for GlobError

fn from(error: BuildError) -> Self

Converts to this type from the input type.

impl From<WalkError> for GlobError

fn from(error: WalkError) -> Self

Converts to this type from the input type.
