Crate willow[−][src]

Expand description

Willow is a library for using the WebGL API in WebAssembly projects. It generates type-safe wrappers for WebAssembly programs using a macro syntax.

Re-exports

pub use anyhow;

This macro allows efficient batch creation of programs by compiling and linking in parallel.

Attribute	In a `Program`-deriving struct, a field of type `Attribute<T>` indicates that the vertex shader has an attribute with the type compatible with `T`.
Buffer	Wraps a WebGL buffer.
Context	A wrapper for a WebGL rendering context.
Error	The `Error` type, a wrapper around a dynamic error type.
Indices	Stores the indices of a buffer.
ProgramData	An internal type used to hold program-specific resources. There must be exactly one field in a `Program`-deriving struct holding `ProgramData` as the value.
Uniform	In a `Program`-deriving struct, a field of type `Uniform<T>` indicates that the vertex shader has a uniform with the type compatible with `T`.

BufferDataUsage	The `usage` parameter passed to `bufferData`.
RenderPrimitiveType	The type of rendering primitive.

AttrStruct	The trait implemented by attribute structs.
AttributeType	Types that can be used as an attribute argument type.
Program	Represents WebGL programs.
UniformType	Types that can be used as a uniform argument type.

Result<T, Error>

Derives a user-friendly wrapper for WebGlProgram from a struct.
