Struct carapax_i18n::Catalog

pub struct Catalog { /* fields omitted */ }

Catalog represents a set of translation strings parsed out of one MO file.

Methods

impl Catalog

pub fn parse<R>(reader: R) -> Result<Catalog, Error> where
    R: Read, 

Parses a gettext catalog from the given binary MO file. Returns the Err variant upon encountering an invalid file format or invalid byte sequence in strings.

Calling this method is equivalent to calling ParseOptions::new().parse(reader).

Examples

use gettext::Catalog;
use std::fs::File;

let file = File::open("french.mo").unwrap();
let catalog = Catalog::parse(file).unwrap();

pub fn gettext(&'a self, msg_id: &'a str) -> &'a str

Returns the singular translation of msg_id from the given catalog or msg_id itself if a translation does not exist.

pub fn ngettext(
    &'a self,
    msg_id: &'a str,
    msg_id_plural: &'a str,
    n: u64
) -> &'a str

Returns the plural translation of msg_id from the given catalog with the correct plural form for the number n of objects. Returns msg_id if a translation does not exist and n == 1, msg_id_plural otherwise.

Currently, the only supported plural formula is n != 1.

pub fn pgettext(&'a self, msg_context: &'a str, msg_id: &'a str) -> &'a str

Returns the singular translation of msg_id in the context msg_context or msg_id itself if a translation does not exist.

pub fn npgettext(
    &'a self,
    msg_context: &'a str,
    msg_id: &'a str,
    msg_id_plural: &'a str,
    n: u64
) -> &'a str

Returns the plural translation of msg_id in the context msg_context with the correct plural form for the number n of objects. Returns msg_id if a translation does not exist and n == 1, msg_id_plural otherwise.

Currently, the only supported plural formula is n != 1.
