Struct Signature

pub struct Signature { /* private fields */ }

Implementations

impl Signature

pub const LEN: usize = 64usize

pub fn from_slice(slice: &[u8]) -> Self

Panics

if the slice is not 64 bytes long.

pub fn to_bytes(&self) -> [u8; 64]

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl<'m> DecodeMessage<'m> for Signature

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> Deserialize<'de> for Signature

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Signature

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

Formats the value using the given formatter.

impl EncodeMessage for Signature

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<'r> FromSql<'r> for Signature

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 FromStr for Signature

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 PartialEq for Signature

fn eq(&self, other: &Signature) -> 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 Serialize for Signature

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl ToSql for Signature

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,

Determines if a value of this type can be converted to the specified Postgres Type.

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

impl TryFrom<&[u8]> for Signature

type Error = TryFromError

The type returned in the event of a conversion error.

fn try_from(v: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Signature

impl StructuralPartialEq for Signature
