Easy access to struct fields in strings
Cargo.toml:
[dependencies]
strung = "0.1.3"
use strung::prelude::*;
#[derive(Strung)]
struct Struct (&'static str, u32);
fn main(){
let s: String = Struct("Bob", 10).strung("{0} is {1}th");
}
#[derive(Strung)]
struct Struct {
name: &'static str,
pos: u32,
}
fn main(){
let s: String = Struct{name:"Bob", pos:10}.strung("{name} is {pos}th.");
}
Prefix and Postix Prefabs
strung():
#[derive(Strung)]
struct Struct (&'static str, u32);
fn main(){
let t = Struct("Bob", 10);
let s = t.strung_curly("{0} is {1}th.");
let s = t.strung_angle("<0> is <1>th.");
let s = t.strung_dollry("${0} is ${1}th.");
let s = t.strung_dollar("$0 is $1th.");
let s = t.strung_hashtag("#0 is #1th.");
}
Custom Prefix and Postix
#[derive(Strung)]
#[strung("<",">")]
struct Struct (&'static str, u32);
fn main(){
let s: String = Struct("Bob", 10).strung("<0> is <1>th.");
}
#[derive(Strung)]
struct Struct (&'static str, u32);
fn main(){
strung::config::static_global("<",">");
let s: String = Struct("Bob", 10).strung_static("<0> is <1>th.");
}
#[derive(Strung)]
struct Struct (&'static str, u32);
fn main(){
let s: String = Struct("Bob", 10).strung_dynamic("<",">","<0> is <1>th.");
}
Cascade
dollar and hashtag prefab!
#[cscd], #[cascade], #[strung(cscd)] or #[strung(cascade)] on a field:
#[derive(Strung)]
struct Struct (&'static str, u32);
#[derive(Strung)]
struct Cascade (u32, #[cscd] Struct);
fn main(){
let s: String = Cascade(11,Struct("Bob", 10))
.strung_dollar("$1.0 is $1.1th for the $0th time!");
}
Ignore
#[igno], #[strung(igno)] or #[strung(ignore)] on a field
#[igno]:
struct NoDisplay;
#[derive(Strung)]
struct Struct (&'static str, u32, #[igno] NoDisplay);
fn main(){
let s: String = Struct("Bob", 10, NoDisplay)
.strung_dollar("$0 is $1th, he won $2!");
}
