Trait sqlx::prelude::Encode[−][src]

pub trait Encode<'q, DB> where
    DB: Database, {
#[must_use]    pub fn encode_by_ref(
        &self, 
        buf: &mut <DB as HasArguments<'q>>::ArgumentBuffer
    ) -> IsNull;

#[must_use]    pub fn encode(
        self, 
        buf: &mut <DB as HasArguments<'q>>::ArgumentBuffer
    ) -> IsNull { ... }

    pub fn produces(&self) -> Option<<DB as Database>::TypeInfo> { ... }

    pub fn size_hint(&self) -> usize { ... }
}

Encode a single value to be sent to the database.

Required methods

#[must_use]pub fn encode_by_ref(
    &self,
    buf: &mut <DB as HasArguments<'q>>::ArgumentBuffer
) -> IsNull[src]

Writes the value of self into buf without moving self.

Where possible, make use of encode instead as it can take advantage of re-using memory.

Provided methods

#[must_use]pub fn encode(
    self,
    buf: &mut <DB as HasArguments<'q>>::ArgumentBuffer
) -> IsNull[src]

Writes the value of self into buf in the expected format for the database.
