Struct mysql_common::named_params::ParsedNamedParams

pub struct ParsedNamedParams<'a> { /* private fields */ }

Parsed named params (see ParsedNamedParams::parse).

Implementations

impl<'a> ParsedNamedParams<'a>

pub fn parse(query: &'a [u8]) -> Result<Self, MixedParamsError>

Parse named params in the given query.

Parameters must be named according to the following convention:

• parameter name must start with either _ or a..z
• parameter name may continue with _, a..z and 0..9

pub fn query(&self) -> &[u8]

Returns a query string to pass to MySql (named parameters have been replaced with ?).

pub fn params(&self) -> &[Cow<'a, [u8]>]

Names of named parameters in order of appearance.

Note

• the returned slice might be empty if original query contained no named parameters.
• same name may appear multiple times.

Trait Implementations

impl<'a> Clone for ParsedNamedParams<'a>

fn clone(&self) -> ParsedNamedParams<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for ParsedNamedParams<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> PartialEq for ParsedNamedParams<'a>

fn eq(&self, other: &ParsedNamedParams<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
