Struct gbm::BufferObjectFlags [−]

pub struct BufferObjectFlags { /* fields omitted */ }

Flags to indicate the intended use for the buffer - these are passed into Device::create_buffer_object.

Use Device::is_format_supported to check if the combination of format and use flags are supported

Methods

`impl BufferObjectFlags`

`const SCANOUT: BufferObjectFlags`

SCANOUT: BufferObjectFlags = BufferObjectFlags{bits: ::ffi::gbm_bo_flags_GBM_BO_USE_SCANOUT as u32,}

Buffer is going to be presented to the screen using an API such as KMS

`const CURSOR: BufferObjectFlags`

CURSOR: BufferObjectFlags = BufferObjectFlags{bits: ::ffi::gbm_bo_flags_GBM_BO_USE_CURSOR as u32,}

Buffer is going to be used as cursor

`const RENDERING: BufferObjectFlags`

RENDERING: BufferObjectFlags = BufferObjectFlags{bits: ::ffi::gbm_bo_flags_GBM_BO_USE_RENDERING as u32,}

Buffer is to be used for rendering - for example it is going to be used as the storage for a color buffer

`const WRITE: BufferObjectFlags`

WRITE: BufferObjectFlags = BufferObjectFlags{bits: ::ffi::gbm_bo_flags_GBM_BO_USE_WRITE as u32,}

Buffer can be used for gbm_bo_write. This is guaranteed to work with BufferObjectFlags::Cursor, but may not work for other combinations.

`const LINEAR: BufferObjectFlags`

LINEAR: BufferObjectFlags = BufferObjectFlags{bits: ::ffi::gbm_bo_flags_GBM_BO_USE_LINEAR as u32,}

Buffer is linear, i.e. not tiled.

`fn empty() -> BufferObjectFlags`

Returns an empty set of flags.

`fn all() -> BufferObjectFlags`

Returns the set containing all flags.

`fn bits(&self) -> u32`

Returns the raw value of the flags currently stored.

`fn from_bits(bits: u32) -> Option<BufferObjectFlags>`

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

`fn from_bits_truncate(bits: u32) -> BufferObjectFlags`

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

`fn is_empty(&self) -> bool`

Returns true if no flags are currently stored.

`fn is_all(&self) -> bool`

Returns true if all flags are currently set.

`fn intersects(&self, other: BufferObjectFlags) -> bool`

Returns true if there are flags common to both self and other.

`fn contains(&self, other: BufferObjectFlags) -> bool`

Returns true all of the flags in other are contained within self.

`fn insert(&mut self, other: BufferObjectFlags)`

Inserts the specified flags in-place.

`fn remove(&mut self, other: BufferObjectFlags)`

Removes the specified flags in-place.

`fn toggle(&mut self, other: BufferObjectFlags)`

Toggles the specified flags in-place.

`fn set(&mut self, other: BufferObjectFlags, value: bool)`

Inserts or removes the specified flags depending on the passed value.
