Struct DDict 

pub struct DDict<'a>(pub(crate) NonNull<ZSTD_DDict_s>, pub(crate) PhantomData<&'a ()>);

A digested decompression dictionary.

Tuple Fields

0: NonNull<ZSTD_DDict_s>

1: PhantomData<&'a ()>

Implementations

impl DDict<'static>

pub fn create(dict_buffer: &[u8]) -> DDict<'static>

Prepare a dictionary to decompress data.

The dictionary content will be copied internally, and does not need to be kept around.

Panics

If loading this dictionary failed. See DDict::try_create.

pub fn try_create(dict_buffer: &[u8]) -> Option<DDict<'static>>

Prepare a dictionary to decompress data.

The dictionary content will be copied internally, and does not need to be kept around. Returns None if zstd could not load the dictionary, for instance because it starts with the dictionary magic number but its header is corrupt.

impl<'a> DDict<'a>

pub fn sizeof(&self) -> usize

pub fn get_dict_id(&self) -> Option<NonZero<u32>>

Returns the dictionary ID for this dict.

Returns None if this dictionary is empty or invalid.

Trait Implementations

impl<'a> Drop for DDict<'a>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
