Implementations

impl<'a> ColumnData<'a>

pub fn is_null(&self) -> bool

pub fn unwrap_text(self) -> Text<'a>

Trait Implementations

impl<'a> Clone for ColumnData<'a>

fn clone(&self) -> ColumnData<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ColumnData<'a>

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

Formats the value using the given formatter.

impl<'a> FromSql<'a> for ColumnData<'a>

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

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

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

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

fn accepts(ty: &Type) -> bool

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

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

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

impl<'a> PartialEq<ColumnData<'a>> for ColumnData<'a>

fn eq(&self, other: &ColumnData<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> ToSql for ColumnData<'a>

fn to_sql( &self, ty: &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
