Struct msql_srv::StatementMetaWriter

#[must_use]
pub struct StatementMetaWriter<'a, W: Write + 'a> { /* fields omitted */ }

Convenience type for responding to a client PREPARE command.

This type should not be dropped without calling reply or error.

Methods

impl<'a, W: Write + 'a> StatementMetaWriter<'a, W>

fn reply<PI, CI>(self, id: u32, params: PI, columns: CI) -> Result<()> where
    PI: IntoIterator<Item = &'a Column>,
    CI: IntoIterator<Item = &'a Column>,
    <PI as IntoIterator>::IntoIter: ExactSizeIterator,
    <CI as IntoIterator>::IntoIter: ExactSizeIterator, 

Reply to the client with the given meta-information.

id is a statement identifier that the client should supply when it later wants to execute this statement. params is a set of Column descriptors for the parameters the client must provide when executing the prepared statement. columns is a second set of Column descriptors for the values that will be returned in each row then the statement is later executed.

fn error<E: ?Sized>(self, kind: ErrorKind, msg: &E) -> Result<()> where
    E: Borrow<[u8]>, 

Reply to the client's PREPARE with an error.
