Struct cloudabi::mflags [−]

#[repr(C)]
pub struct mflags { /* fields omitted */ }

Memory mapping flags.

Methods

`impl mflags`

`const ANON: mflags`

ANON: mflags = mflags{bits: 1,}

Instead of mapping the contents of the file provided, create a mapping to anonymous memory. The file descriptor argument must be set to MAP_ANON_FD, and the offset must be set to zero.

`const FIXED: mflags`

FIXED: mflags = mflags{bits: 2,}

Require that the mapping is performed at the base address provided.

`const PRIVATE: mflags`

PRIVATE: mflags = mflags{bits: 4,}

Changes are private.

`const SHARED: mflags`

SHARED: mflags = mflags{bits: 8,}

Changes are shared.

`fn empty() -> mflags`

Returns an empty set of flags.

`fn all() -> mflags`

Returns the set containing all flags.

`fn bits(&self) -> u8`

Returns the raw value of the flags currently stored.

`fn from_bits(bits: u8) -> Option<mflags>`

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

`fn from_bits_truncate(bits: u8) -> mflags`

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: mflags) -> bool`

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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