row: Option<&'r Bytes>

type_info: PgTypeInfo

format: PgValueFormat

Implementations

impl<'r> PgValueRef<'r>

pub fn format(&self) -> PgValueFormat

pub fn as_bytes(&self) -> Result<&'r [u8], Box<dyn Error + Send + Sync>>

Trait Implementations

impl<'r> Clone for PgValueRef<'r>

fn clone(&self) -> PgValueRef<'r>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'r> ValueRef<'r> for PgValueRef<'r>

type Database = Postgres

fn to_owned(&self) -> PgValue

Creates an owned value from this value reference.

fn type_info(&self) -> Cow<'_, PgTypeInfo>

Get the type information for this value.

fn is_null(&self) -> bool

Returns true if the SQL value is NULL.
