Struct Declaration 

pub struct Declaration<'a> { /* private fields */ }

What a build script declares, before Declaration::emit writes it out.

Implementations

impl<'a> Declaration<'a>

pub const fn demanding(self, demands: &'a [Demand]) -> Declaration<'a>

Adds the hardware the application cannot run without.

pub const fn opening(self, opens: &'a [&'a str]) -> Declaration<'a>

Adds the media types of the files the application opens, such as "audio/*", so the platform offers it for them.

pub fn emit(self)

Writes the declaration where the application and every platform build reads it.

Call this from a build script. It panics when the files cannot be written, which is what a build script does with a failure.

Trait Implementations

impl<'a> Clone for Declaration<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for Declaration<'a>

impl<'a> Debug for Declaration<'a>

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

Formats the value using the given formatter.
