Struct mz_pgrepr::UInt4

pub struct UInt4(pub u32);

A wrapper for 32-bit unsigned integers that can be serialized to and deserialized from the PostgreSQL binary format.

Tuple Fields

0: u32

Trait Implementations

impl Clone for UInt4

fn clone(&self) -> UInt4

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UInt4

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

Formats the value using the given formatter.

impl<'a> FromSql<'a> for UInt4

fn from_sql( _: &Type, raw: &'a [u8] ) -> Result<UInt4, 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 ToSql for UInt4

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

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

fn accepts(ty: &Type) -> bool

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
