Route match information

If resource path contains variable patterns, Params stores this variables.

Methods

impl Params

[−]

pub fn is_empty(&self) -> bool

[−]

Check if there are any matched patterns

pub fn len(&self) -> usize

[−]

Check number of extracted parameters

pub fn get(&self, key: &str) -> Option<&str>

[−]

Get matched parameter by name without type conversion

pub fn unprocessed(&self) -> &str

[−]

Get unprocessed part of path

pub fn query<T: FromParam>(&self, key: &str) -> Result<T, <T as FromParam>::Err>

[−]

Get matched FromParam compatible parameter by name.

If keyed parameter is not available empty string is used as default value.

fn index(req: HttpRequest) -> Result<String> {
    let ivalue: isize = req.match_info().query("val")?;
    Ok(format!("isuze value: {:?}", ivalue))
}

pub fn iter(&self) -> ParamsIter

[−]

Return iterator to items in parameter container
