Struct gstreamer::MemoryFlags

pub struct MemoryFlags { /* fields omitted */ }

Flags for wrapped memory.

Implementations

impl MemoryFlags

pub const READONLY: MemoryFlags

memory is readonly. It is not allowed to map the memory with [crate::MapFlags::Write].

pub const NO_SHARE: MemoryFlags

memory must not be shared. Copies will have to be made when this memory needs to be shared between buffers.

pub const ZERO_PREFIXED: MemoryFlags

the memory prefix is filled with 0 bytes

pub const ZERO_PADDED: MemoryFlags

the memory padding is filled with 0 bytes

pub const PHYSICALLY_CONTIGUOUS: MemoryFlags

the memory is physically contiguous. (Since: 1.2)

pub const NOT_MAPPABLE: MemoryFlags

the memory can’t be mapped via [crate::Memory::map()] without any preconditions. (Since: 1.2)

pub const fn empty() -> MemoryFlags

Returns an empty set of flags

pub const fn all() -> MemoryFlags

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<MemoryFlags>

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

pub const fn from_bits_truncate(bits: u32) -> MemoryFlags

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

pub const unsafe fn from_bits_unchecked(bits: u32) -> MemoryFlags

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: MemoryFlags) -> bool

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

pub const fn contains(&self, other: MemoryFlags) -> bool

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

pub fn insert(&mut self, other: MemoryFlags)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: MemoryFlags)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: MemoryFlags)

Toggles the specified flags in-place.

pub fn set(&mut self, other: MemoryFlags, value: bool)

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