Enum rustc_error_messages::FluentError

pub enum FluentError {
    Overriding {
        kind: EntryKind,
        id: String,
    },
    ParserError(ParserError),
    ResolverError(ResolverError),
}

Core error type for Fluent runtime system.

It contains three main types of errors that may come up during runtime use of the fluent-bundle crate.

Variants

Overriding

Fields

kind: EntryKind

id: String

An error which occurs when FluentBundle::add_resource adds entries that are already registered in a given FluentBundle.

Example

use fluent_bundle::{FluentBundle, FluentResource};
use unic_langid::langid;

let ftl_string = String::from("intro = Welcome, { $name }.");
let res1 = FluentResource::try_new(ftl_string)
    .expect("Could not parse an FTL string.");

let ftl_string = String::from("intro = Hi, { $name }.");
let res2 = FluentResource::try_new(ftl_string)
    .expect("Could not parse an FTL string.");

let langid_en = langid!("en-US");
let mut bundle = FluentBundle::new(vec![langid_en]);

bundle.add_resource(&res1)
    .expect("Failed to add FTL resources to the bundle.");

assert!(bundle.add_resource(&res2).is_err());

Trait Implementations

impl Clone for FluentError

fn clone(&self) -> FluentError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FluentError

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

Formats the value using the given formatter.

impl Display for FluentError

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

Formats the value using the given formatter.

impl Error for FluentError

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<ParserError> for FluentError

fn from(error: ParserError) -> FluentError

Converts to this type from the input type.

impl From<ResolverError> for FluentError

fn from(error: ResolverError) -> FluentError

Converts to this type from the input type.

impl PartialEq for FluentError

fn eq(&self, other: &FluentError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for FluentError

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
