Trait Implementations

impl Clone for CompressionType

fn clone(&self) -> CompressionType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CompressionType

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

Formats the value using the given formatter.

impl Default for CompressionType

fn default() -> CompressionType

Returns the “default value” for a type.

impl EndianScalar for CompressionType

type Scalar = i8

fn to_little_endian(self) -> i8

fn from_little_endian(v: i8) -> CompressionType

impl<'a> Follow<'a> for CompressionType

type Inner = CompressionType

unsafe fn follow( buf: &'a [u8], loc: usize ) -> <CompressionType as Follow<'a>>::Inner

Safety

impl Hash for CompressionType

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 CompressionType

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for CompressionType

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for CompressionType

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Push for CompressionType

type Output = CompressionType

unsafe fn push(&self, dst: &mut [u8], _written_len: usize)

Safety

fn size() -> usize

fn alignment() -> PushAlignment

impl<'a> Verifiable for CompressionType

fn run_verifier( v: &mut Verifier<'_, '_>, pos: usize ) -> Result<(), InvalidFlatbuffer>

Runs the verifier for this type, assuming its at position pos in the verifier’s buffer. Should not need to be called directly.
