Struct LanguageMap 

pub struct LanguageMap { /* private fields */ }

Maps file extensions and extensionless file names to language ids.

Examples

use std::path::Path;

use mcpls_core::config::{FileName, LanguageId, LanguageMap, PatternTarget};

let mut map = LanguageMap::default();
map.insert(
    PatternTarget::Name(FileName::from_static("Makefile")),
    LanguageId::new("make").unwrap(),
);
assert_eq!(map.detect(Path::new("Makefile")), "make");
assert_eq!(map.detect(Path::new("main.rs")), LanguageId::PLAINTEXT);

Implementations

impl LanguageMap

pub fn insert(&mut self, target: PatternTarget, language: LanguageId)

Maps target to language, replacing an earlier mapping of the same extension or name.

pub fn detect(&self, path: &Path) -> LanguageId

The language of path, or LanguageId::PLAINTEXT when its extension or name is not mapped.

pub fn languages(&self) -> impl Iterator<Item = &LanguageId>

Every language some extension or name maps to, with repeats when several keys map to one language.
