[−][src]Struct seahorse::Context
Context
type
This type is used only for Action
arguments
Fields
args: Vec<String>
Vec<String>
with flags and flag values removed from command line arguments
Methods
impl Context
[src]
pub fn new(args: Vec<String>, flags: Option<Vec<Flag>>) -> Self
[src]
Create new instance of Context
Parse processing using Vec<String>
command line argument and Vec<Flag>
as arguments
Example
use std::env; use seahorse::{Context, Flag, FlagType}; let args: Vec<String> = env::args().collect(); let flag = Flag::new("bool", "cli cmd [arg] --bool", FlagType::Bool); let context = Context::new(args, Some(vec![flag]));
pub fn bool_flag(&self, name: &str) -> bool
[src]
Get bool flag
Example
use std::env; use seahorse::{Context, Flag, FlagType}; let args: Vec<String> = env::args().collect(); let flag = Flag::new("bool", "cli cmd [arg] --bool", FlagType::Bool); let context = Context::new(args, Some(vec![flag])); if context.bool_flag("bool") { println!("true"); }
pub fn string_flag(&self, name: &str) -> Option<String>
[src]
Get string flag
Example
use std::env; use seahorse::{Context, Flag, FlagType}; let args: Vec<String> = env::args().collect(); let flag = Flag::new("string", "cli cmd [arg] --string [string]", FlagType::String); let context = Context::new(args, Some(vec![flag])); match context.string_flag("string") { Some(s) => println!("{}", s), None => println!("Not found string...") }
pub fn int_flag(&self, name: &str) -> Option<isize>
[src]
Get int flag
Example
use std::env; use seahorse::{Context, Flag, FlagType}; let args: Vec<String> = env::args().collect(); let flag = Flag::new("int", "cli cmd [arg] --int [int]", FlagType::Int); let context = Context::new(args, Some(vec![flag])); match context.int_flag("int") { Some(i) => println!("{}", i), None => println!("Not found int number...") }
pub fn float_flag(&self, name: &str) -> Option<f64>
[src]
Get float flag
Example
use std::env; use seahorse::{Context, Flag, FlagType}; let args: Vec<String> = env::args().collect(); let flag = Flag::new("float", "cli cmd [arg] --float [float]", FlagType::Float); let context = Context::new(args, Some(vec![flag])); match context.float_flag("float") { Some(f) => println!("{}", f), None => println!("Not found float number...") }
