A positional-argument validator with a namespace name.

Implementations

impl Argu

pub fn new(name: impl Into<String>) -> Argu

pub fn validate<I, K, S>( &self, args: Vec<Value>, whence: &str, spec: I, ) -> Result<Map, ArguError>

where I: IntoIterator<Item = (K, S)>, K: Into<String>, S: Into<Spec>,

Match the arguments against the spec, naming the call whence.

pub fn signature<I, K, S>( &self, whence: &str, spec: I, ) -> Result<Signature, ArguError>

where I: IntoIterator<Item = (K, S)>, K: Into<String>, S: Into<Spec>,

Compile the spec once, for many calls.
