Struct nix::fcntl::FallocateFlags[][src]

pub struct FallocateFlags { /* fields omitted */ }

Mode argument flags for fallocate determining operation performed on a given range.

Implementations

impl FallocateFlags[src]

pub const FALLOC_FL_KEEP_SIZE: FallocateFlags[src]

File size is not changed.

offset + len can be greater than file size.

pub const FALLOC_FL_PUNCH_HOLE: FallocateFlags[src]

Deallocates space by creating a hole.

Must be ORed with FALLOC_FL_KEEP_SIZE. Byte range starts at offset and continues for len bytes.

pub const FALLOC_FL_COLLAPSE_RANGE: FallocateFlags[src]

Removes byte range from a file without leaving a hole.

Byte range to collapse starts at offset and continues for len bytes.

pub const FALLOC_FL_ZERO_RANGE: FallocateFlags[src]

Zeroes space in specified byte range.

Byte range starts at offset and continues for len bytes.

pub const FALLOC_FL_INSERT_RANGE: FallocateFlags[src]

Increases file space by inserting a hole within the file size.

Does not overwrite existing data. Hole starts at offset and continues for len bytes.

pub const FALLOC_FL_UNSHARE_RANGE: FallocateFlags[src]

Shared file data extants are made private to the file.

Gaurantees that a subsequent write will not fail due to lack of space.

pub const fn empty() -> FallocateFlags[src]

Returns an empty set of flags

pub const fn all() -> FallocateFlags[src]

Returns the set containing all flags.

pub const fn bits(&self) -> c_int[src]

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: c_int) -> Option<FallocateFlags>[src]

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

pub const fn from_bits_truncate(bits: c_int) -> FallocateFlags[src]

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

pub const unsafe fn from_bits_unchecked(bits: c_int) -> FallocateFlags[src]

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

pub const fn is_empty(&self) -> bool[src]

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool[src]

Returns true if all flags are currently set.

pub const fn intersects(&self, other: FallocateFlags) -> bool[src]

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

pub const fn contains(&self, other: FallocateFlags) -> bool[src]

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

pub fn insert(&mut self, other: FallocateFlags)[src]

Inserts the specified flags in-place.

pub fn remove(&mut self, other: FallocateFlags)[src]

Removes the specified flags in-place.

pub fn toggle(&mut self, other: FallocateFlags)[src]

Toggles the specified flags in-place.

pub fn set(&mut self, other: FallocateFlags, value: bool)[src]

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