Trait Implementations

impl<T: Debug> Debug for Record<T>

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

Formats the value using the given formatter.

impl<'a> FromSql<'a> for Record<()>

fn from_sql( _: &Type, raw: &'a [u8], ) -> Result<Record<()>, 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 + Sync + Send>>

impl<T: PartialEq> PartialEq for Record<T>

fn eq(&self, other: &Record<T>) -> 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.
