Struct ZstdOptions 

pub struct ZstdOptions {
    pub level: Option<i32>,
    pub checksum: bool,
    pub dictionary_id: Option<u32>,
    pub frame_kind: ZstdFrameKind,
}

Zstd option metadata.

Fields

level: Option<i32>

Numeric zstd compression level, when specified by the caller.

checksum: bool

Whether a checksum should be described as present.

dictionary_id: Option<u32>

Optional dictionary identifier.

frame_kind: ZstdFrameKind

Frame shape label.

Implementations

impl ZstdOptions

pub const fn new() -> ZstdOptions

Creates default zstd option metadata.

pub const fn with_level(self, level: i32) -> ZstdOptions

Adds a numeric compression level label.

pub const fn with_checksum(self, checksum: bool) -> ZstdOptions

Sets whether checksum metadata is present.

pub const fn with_dictionary_id(self, dictionary_id: u32) -> ZstdOptions

Adds a dictionary identifier.

pub const fn with_frame_kind(self, frame_kind: ZstdFrameKind) -> ZstdOptions

Sets the frame shape label.

Trait Implementations

impl Clone for ZstdOptions

fn clone(&self) -> ZstdOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ZstdOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for ZstdOptions

fn default() -> ZstdOptions

Returns the “default value” for a type.

impl Hash for ZstdOptions

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ZstdOptions

fn cmp(&self, other: &ZstdOptions) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ZstdOptions

fn eq(&self, other: &ZstdOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ZstdOptions

fn partial_cmp(&self, other: &ZstdOptions) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
