Implementations§

source§

impl<'a> QueryEvent<'a>

source

pub fn new( status_vars: impl Into<Cow<'a, [u8]>>, schema: impl Into<Cow<'a, [u8]>>, ) -> QueryEvent<'a>

Creates a new instance.

source

pub fn with_thread_id(self, thread_id: u32) -> QueryEvent<'a>

Sets the thread_id value.

source

pub fn with_execution_time(self, execution_time: u32) -> QueryEvent<'a>

Sets the execution_time value.

source

pub fn with_error_code(self, error_code: u16) -> QueryEvent<'a>

Sets the error_code value.

source

pub fn with_status_vars( self, status_vars: impl Into<Cow<'a, [u8]>>, ) -> QueryEvent<'a>

Sets the status_vars value (max length is `u16::MAX).

source

pub fn with_schema(self, schema: impl Into<Cow<'a, [u8]>>) -> QueryEvent<'a>

Sets the schema value (max length is `u8::MAX).

source

pub fn with_query(self, query: impl Into<Cow<'a, [u8]>>) -> QueryEvent<'a>

Sets the query value.

source

pub fn thread_id(&self) -> u32

Returns the thread_id value.

thread_id is the ID of the thread that issued this statement. It is needed for temporary tables.

source

pub fn execution_time(&self) -> u32

Returns the execution_time value.

execution_time is the time from when the query started to when it was logged in the binlog, in seconds.

source

pub fn error_code(&self) -> u16

Returns the error_code value.

error_code is the error code generated by the master. If the master fails, the slave will fail with the same error code.

source

pub fn status_vars_raw(&'a self) -> &'a [u8]

Returns the status_vars value.

status_vars contains zero or more status variables. Each status variable consists of one byte identifying the variable stored, followed by the value of the variable.

source

pub fn status_vars(&'a self) -> &'a StatusVars<'a>

Returns an iterator over status variables.

source

pub fn schema_raw(&'a self) -> &'a [u8]

Returns the schema value.

schema is schema name.

source

pub fn schema(&'a self) -> Cow<'a, str>

Returns the schema value as a string (lossy converted).

source

pub fn query_raw(&'a self) -> &'a [u8]

Returns the query value.

query is the corresponding LOAD DATA INFILE statement.

source

pub fn query(&'a self) -> Cow<'a, str>

Returns the query value as a string (lossy converted).

source

pub fn into_owned(self) -> QueryEvent<'static>
