Struct HalfVector

pub struct HalfVector(/* private fields */);

A half vector.

Implementations

impl HalfVector

pub fn from_f32_slice(slice: &[f32]) -> HalfVector

Creates a half vector from a f32 slice.

pub fn to_vec(&self) -> Vec<f16>

Returns a copy of the half vector as a Vec<f16>.

pub fn as_slice(&self) -> &[f16]

Returns the half vector as a slice.

Trait Implementations

impl Clone for HalfVector

fn clone(&self) -> HalfVector

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HalfVector

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

Formats the value using the given formatter.

impl From<HalfVector> for Vec<f16>

fn from(val: HalfVector) -> Vec<f16>

Converts to this type from the input type.

impl From<Vec<f16>> for HalfVector

fn from(v: Vec<f16>) -> HalfVector

Converts to this type from the input type.

impl<'a> FromSql<'a> for HalfVector

fn from_sql( _ty: &Type, raw: &'a [u8], ) -> Result<HalfVector, Box<dyn Error + Send + Sync>>

Creates a new value of this type from a buffer of data of the specified Postgres Type in its binary format.

fn accepts(ty: &Type) -> bool

Determines if a value of this type can be created from the specified Postgres Type.

fn from_sql_null(ty: &Type) -> Result<Self, Box<dyn Error + Send + Sync>>

Creates a new value of this type from a NULL SQL value.

fn from_sql_nullable( ty: &Type, raw: Option<&'a [u8]>, ) -> Result<Self, Box<dyn Error + Send + Sync>>

A convenience function that delegates to from_sql and from_sql_null depending on the value of raw.

impl PartialEq for HalfVector

fn eq(&self, other: &HalfVector) -> 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.
