Enum fluent_bundle::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

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.

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

Performs copy-assignment from source.

impl Debug for FluentError

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

Formats the value using the given formatter.

impl Display for FluentError

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

Formats the value using the given formatter.

impl Error for FluentError

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<ParserError> for FluentError

fn from(error: ParserError) -> Self

Performs the conversion.

impl PartialEq<FluentError> 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: &FluentError) -> bool

This method tests for !=.
