Expand description

An owned value from the database.

Associated Types

Required methods

Get this value as a reference.

Get the type information for this value.

Returns true if the SQL value is NULL.

Provided methods

Decode this single value into the requested type.

Panics

Panics if the value cannot be decoded into the requested type. See try_decode for a non-panicking version.

Decode this single value into the requested type.

Unlike decode, this method does not check that the type of this value is compatible with the Rust type and blindly tries to decode the value.

Panics

Panics if the value cannot be decoded into the requested type. See try_decode_unchecked for a non-panicking version.

Decode this single value into the requested type.

Errors
  • Decode if the value could not be decoded into the requested type.

Decode this single value into the requested type.

Unlike try_decode, this method does not check that the type of this value is compatible with the Rust type and blindly tries to decode the value.

Errors
