pub struct Builder<'a>(_);

Methods

impl<'a> Builder<'a>

pub fn create<T>(&self, len: usize, usage: GLenum) -> Result<BufferObject<T>>

[−]

Creates a new buffer and allocates it with enough capacity to hold len elements of type T

equivalent to glGenBuffers/glCreateBuffers + gl(Named)BufferData

pub fn create_target<T>(     &self,     len: usize,     usage: GLenum,     target: GLenum ) -> Result<BufferObject<T>>

[−]

Creates a new buffer and allocates it with enough capacity to hold len elements of type T

equivalent to glGenBuffers/glCreateBuffers + gl(Named)BufferData. target specifies the target to which to bind the buffer before creation. This is only useful with no DSA where in certain platforms you can't change the target initially bound

pub fn empty<T>(&self) -> Result<BufferObject<T>>

[−]

Creates an empty buffer

Call load after empty to actually allocate the buffer with enough capacity

equivalent to glGenBuffers/glCreateBuffers

pub fn empty_target<T>(&self, target: GLenum) -> Result<BufferObject<T>>

[−]

Creates an empty buffer

Call load after empty to actually allocate the buffer with enough capacity

equivalent to glGenBuffers/glCreateBuffers

pub fn from_data<T: 'static>(     &self,     data: &[T],     usage: GLenum ) -> Result<BufferObject<T>>

[−]

Creates a buffer, allocates it and loads the data passed as parameter in it

equivalent to glGenBuffers/glCreateBuffers + gl(Named)BufferData

pub fn from_data_target<T: 'static>(     &self,     data: &[T],     usage: GLenum,     target: GLenum ) -> Result<BufferObject<T>>

[−]

Creates a buffer, allocates it and loads the data passed as parameter in it

equivalent to glGenBuffers/glCreateBuffers + gl(Named)BufferData

pub fn create_immutable<T>(     &self,     len: usize,     flags: GLbitfield ) -> Result<BufferObjectImmutable<T>>

[−]

Allocates a buffer with enough capacity to hold len elemnts of type T

see gl(Named)BufferStorage

pub fn create_immutable_target<T>(     &self,     len: usize,     flags: GLbitfield,     target: GLenum ) -> Result<BufferObjectImmutable<T>>

[−]

Allocates a buffer with enough capacity to hold len elemnts of type T

see gl(Named)BufferStorage

pub fn immutable_from_data<T>(     &self,     data: &[T],     flags: GLbitfield ) -> Result<BufferObjectImmutable<T>>

[−]

Allocates a buffer and loads the passed data in it

see gl(Named)BufferStorage
