Trait Implementations

impl<const S: usize> AsRef<[u8]> for Token<S>

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl<const S: usize> Clone for Token<S>

fn clone(&self) -> Token<S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const S: usize> Debug for Token<S>

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

Formats the value using the given formatter.

impl<'m, const SI: usize> DecodeMessage<'m> for Token<SI>

const WIRE_TYPE: WireType = WireType::Len

This field is just a hint, merge might accept another type

fn decode_default() -> Self

fn merge( &mut self, kind: FieldKind<'m>, is_field: bool, ) -> Result<(), DecodeError>

kind does not need to be the same as Self::WIRE_TYPE

fn parse_from_bytes(b: &'m [u8]) -> Result<Self, DecodeError>

where Self: Sized,

impl<'de, const S: usize> Deserialize<'de> for Token<S>

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<const S: usize> Display for Token<S>

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

Formats the value using the given formatter.

impl<const SI: usize> EncodeMessage for Token<SI>

const WIRE_TYPE: WireType = WireType::Len

at the moment only used to check if this message can be packed

fn is_default(&self) -> bool

fn encoded_size( &mut self, field: Option<FieldOpt>, builder: &mut SizeBuilder, ) -> Result<(), EncodeError>

how big will the size be after encoding

fn encode<B>( &mut self, field: Option<FieldOpt>, encoder: &mut MessageEncoder<B>, ) -> Result<(), EncodeError>

where B: BytesWrite,

In most cases before this is called encoded_size get’s called

fn write_to_bytes(&mut self) -> Result<Vec<u8>, EncodeError>

impl<const S: usize> From<[u8; S]> for Token<S>

fn from(bytes: [u8; S]) -> Self

Converts to this type from the input type.

impl<'r, const SI: usize> FromSql<'r> for Token<SI>

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

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<const S: usize> FromStr for Token<S>

type Err = DecodeError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl<const S: usize> Hash for Token<S>

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<const S: usize> PartialEq for Token<S>

fn eq(&self, other: &Token<S>) -> 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<const SI: usize> Serialize for Token<SI>

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<const SI: usize> ToSql for Token<SI>

fn to_sql( &self, ty: &Type, out: &mut BytesMut, ) -> Result<IsNull, Box<dyn Error + Sync + Send>>

where Self: Sized,

Converts the value of self into the binary format of the specified Postgres Type, appending it to out.

fn accepts(ty: &Type) -> bool

where Self: Sized,

fn to_sql_checked( &self, ty: &Type, out: &mut BytesMut, ) -> Result<IsNull, Box<dyn Error + Sync + Send>>

An adaptor method used internally by Rust-Postgres.

fn encode_format(&self, _ty: &Type) -> Format

Specify the encode format
