Trait sqlx_core::decode::Decode

pub trait Decode<DB: ?Sized>: Sized where
    DB: Database, {
    fn decode(raw: &[u8]) -> Result<Self, DecodeError>;

    fn decode_null() -> Result<Self, DecodeError> { ... }
    fn decode_nullable(raw: Option<&[u8]>) -> Result<Self, DecodeError> { ... }
}

Decode a single value from the database.

Required methods

Provided methods

fn decode_null() -> Result<Self, DecodeError>

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

The default implementation returns DecodeError::UnexpectedNull.
