    // some fields omitted
}

Implementations

impl Context

pub fn new(
    args: Vec<String>,
    flags: Option<Vec<Flag>>,
    help_text: String
) -> Self

pub fn bool_flag(&self, name: &str) -> bool

Get bool flag

Example

use seahorse::Context;

fn action(c: &Context) {
    if c.bool_flag("bool") {
        println!("True!");
    } else {
        println!("False!");
    }
}

pub fn string_flag(&self, name: &str) -> Result<String, FlagError>

Get string flag

Example

use seahorse::Context;

fn action(c: &Context) {
    match c.string_flag("string") {
        Ok(s) => println!("{}", s),
        Err(e) => println!("{}", e)
    }
}

pub fn int_flag(&self, name: &str) -> Result<isize, FlagError>

fn action(c: &Context) {
    match c.int_flag("int") {
        Ok(i) => println!("{}", i),
        Err(e) => println!("{}", e)
    }
}

fn action(c: &Context) {
    match c.float_flag("float") {
        Ok(f) => println!("{}", f),
        Err(e) => println!("{}", e)
    }
}
