Struct OptionQuery 

#[non_exhaustive]
pub struct OptionQuery {
    pub q: String,
    pub values: Vec<String>,
}

What a searchable select asks for, from the query string: q, the text typed (trimmed; empty when the list just opened), or values, the options whose labels the page needs (after a failed submit, the values sent back have no label yet).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

q: String

The text typed, trimmed.

values: Vec<String>

Values to look up (?values=3&values=5), when this is a lookup.

Implementations

impl OptionQuery

pub fn is_lookup(&self) -> bool

Whether the select asks for labels of known values rather than searching: answer with exactly those options.

pub fn values_as<T: FromStr>(&self) -> Vec<T>

The looked-up values parsed as the key type (i64 ids), skipping any that don’t parse, so the query binds them typed (PostgreSQL won’t compare a BIGINT with text).

pub fn parse(query: &str) -> Self

Reads a query string (q=kop, values=3&values=5).

Trait Implementations

impl Clone for OptionQuery

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionQuery

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

Formats the value using the given formatter.

impl Default for OptionQuery

fn default() -> Self

Returns the “default value” for a type.

impl Eq for OptionQuery

impl<S: Send + Sync> FromRequestParts<S> for OptionQuery

type Rejection = !

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.

async fn from_request_parts( parts: &mut Parts, _: &S, ) -> Result<Self, Infallible>

Perform the extraction.

impl PartialEq for OptionQuery

fn eq(&self, other: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.
