Implementations

impl MetadataVersion

pub const V1: Self = _

0.1.0 (October 2016).

pub const V2: Self = _

0.2.0 (February 2017). Non-backwards compatible with V1.

pub const V3: Self = _

0.3.0 -> 0.7.1 (May - December 2017). Non-backwards compatible with V2.

pub const V4: Self = _

= 0.8.0 (December 2017). Non-backwards compatible with V3.

pub const V5: Self = _

= 1.0.0 (July 2020). Backwards compatible with V4 (V5 readers can read V4 metadata and IPC messages). Implementations are recommended to provide a V4 compatibility mode with V5 format changes disabled.

Incompatible changes between V4 and V5:

• Union buffer layout has changed. In V5, Unions don’t have a validity bitmap buffer.

pub const ENUM_MIN: i16 = 0i16

pub const ENUM_MAX: i16 = 4i16

pub const ENUM_VALUES: &'static [Self] = _

pub fn variant_name(self) -> Option<&'static str>

Returns the variant’s name or “” if unknown.

Trait Implementations

impl Clone for MetadataVersion

fn clone(&self) -> MetadataVersion

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataVersion

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

Formats the value using the given formatter.

impl Default for MetadataVersion

fn default() -> MetadataVersion

Returns the “default value” for a type.

impl EndianScalar for MetadataVersion

type Scalar = i16

fn to_little_endian(self) -> i16

fn from_little_endian(v: i16) -> Self

impl<'a> Follow<'a> for MetadataVersion

type Inner = MetadataVersion

unsafe fn follow(buf: &'a [u8], loc: usize) -> Self::Inner

Safety

impl Hash for MetadataVersion

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

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 MetadataVersion

fn cmp(&self, other: &MetadataVersion) -> 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 MetadataVersion

fn eq(&self, other: &MetadataVersion) -> 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 MetadataVersion

fn partial_cmp(&self, other: &MetadataVersion) -> 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.

impl Push for MetadataVersion

type Output = MetadataVersion

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

Safety

fn size() -> usize

fn alignment() -> PushAlignment

impl<'a> Verifiable for MetadataVersion

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.
