Required Methods§
Provided Methods§
Sourcefn from_sql_zoned(oid: Oid, buf: &[u8], zone: TimeZone) -> Result<Self, Error>
fn from_sql_zoned(oid: Oid, buf: &[u8], zone: TimeZone) -> Result<Self, Error>
Decodes a non-null value, using zone to interpret zone-less temporal
values (timestamp, date, time).
The default implementation ignores zone.
Sourcefn from_sql_null() -> Result<Self, Error>
fn from_sql_null() -> Result<Self, Error>
Decodes SQL NULL.
The default implementation errors; Option<T> overrides it to return
None.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
