Struct FileExtension 

pub struct FileExtension(/* private fields */);

A file extension as Path::extension reports it: no leading dot, and only ASCII letters, digits, _, - and +, so no glob or path characters that make a pattern ambiguous.

extensions = [".rs"] would load but never match, so a leading dot is rejected at load time. Case is significant, as in the extension map.

Examples

use mcpls_core::config::FileExtension;

assert_eq!(FileExtension::new("rs").unwrap(), "rs");
assert!(FileExtension::new(".rs").is_err());
assert!(FileExtension::new("{cpp,h}").is_err());

Implementations

impl FileExtension

pub const fn from_static(text: &'static str) -> Self

Builds the value from a literal, checked at compile time when evaluated in a const context.

Panics

Panics if the literal is not a valid value of this type.

pub fn new(text: impl Into<String>) -> Result<Self, InvalidFileExtension>

Builds the value from any string.

Errors

Returns InvalidFileExtension naming the first rule text breaks.

impl FileExtension

pub fn as_str(&self) -> &str

The validated text.
