Implementations

impl Components

const fn letter_component(letter: char) -> Option<SwizzleComponent>

fn single_component(name: &str, name_span: Span) -> Result<u32, Error<'_>>

fn new(name: &str, name_span: Span) -> Result<Self, Error<'_>>

Construct a Components value from a ‘member’ name, like "wzy" or "x".

Use name_span for reporting errors in parsing the component string.
