Struct citro3d::shader::Library

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

A PICA200 Shader Library (commonly called DVLB). This can be comprised of one or more Entrypoints, but most commonly has one vertex shader and an optional geometry shader.

This is the result of parsing a shader binary (.shbin), and the resulting Entrypoints can be used as part of a Program.

Implementations

impl Library

pub fn from_bytes(bytes: &[u8]) -> Result<Self, Box<dyn Error>>

Parse a new shader library from input bytes.

Errors

An error is returned if the input data does not have an alignment of 4 (cannot be safely converted to &[u32]).

pub fn len(&self) -> usize

Get the number of Entrypoints in this shader library.

pub fn is_empty(&self) -> bool

Whether the library has any Entrypoints or not.

pub fn get(&self, index: usize) -> Option<Entrypoint<'_>>

Get the Entrypoint at the given index, if present.

Trait Implementations

impl Drop for Library

fn drop(&mut self)

Executes the destructor for this type.
