Implementations§

Source

pub fn from_banner_type(banner_type: BannerType) -> Self

Create new banner from BannerType BannerType can be one of the following:

BannerType::Standard
BannerType::Limited
You have to set operator pool and operator rate up using set_pool and set_rate_up yourself
The only diffirent is rate_up_rate. 70% up for 6 star operator in Limited and 50% up for 6 star operator in Standard. Both have 50% rate up rate for 5 star operator

§Example

use prts::{Banner, BannerType};
 
let mut banner = Banner::from_banner_type(BannerType::Limited);

Source

pub fn from_file(file_name: String) -> Self

Create new instance of Banner by read .toml file
See sample file

§Example

use prts::Banner;
 
let mut banner = Banner::from_file("./data/operators.toml".to_string());
let (star, opname, is_up) = banner.gacha_operator();
println!("{} {} {}", is_up, star, opname);

Source

pub fn set_pool(&mut self, star: u8, operators: Vec<String>)

Set banner pool with specific operator bound to specific star

§Example

use prts::{Banner, BannerType};
 
let mut banner = Banner::from_banner_type(BannerType::Standard);
// set pool 6 star have 2 operators 
banner.set_pool(6, vec!["Silver Ash".to_string(), "Angelina".to_string()]);
// set pool 5 star have 2 operators 
banner.set_pool(5, vec!["Andreana".to_string(), "Projekt Red".to_string()]);
// set pool 4 star have 2 operators 
banner.set_pool(4, vec!["Utage".to_string(), "Myrtle".to_string()]);
// set pool 3 star have 2 operators 
banner.set_pool(3, vec!["Lava".to_string(), "Hibicus".to_string()]);
 
// set rate up 6 star have 2 operator
banner.set_rate_up(6, vec!["Surtr".to_string(), "Skadi".to_string()]);
// set rate up 5 star have 3 operator
banner.set_rate_up(5, vec!["Specter".to_string(), "Ptilopsis".to_string(), "Lappland".to_string()]);
 
let (star, opname, is_up) = banner.gacha_operator();
println!("{} {} {}", is_up, star, opname);

Source

pub fn set_rate_up(&mut self, star: u8, rateup_operators: Vec<String>)

Set banner rate up operator with specific operator bound to specific star

§Example

use prts::{Banner, BannerType};
 
let mut banner = Banner::from_banner_type(BannerType::Standard);
// set pool 6 star have 2 operators 
banner.set_pool(6, vec!["Silver Ash".to_string(), "Angelina".to_string()]);
// set pool 5 star have 2 operators 
banner.set_pool(5, vec!["Andreana".to_string(), "Projekt Red".to_string()]);
// set pool 4 star have 2 operators 
banner.set_pool(4, vec!["Utage".to_string(), "Myrtle".to_string()]);
// set pool 3 star have 2 operators 
banner.set_pool(3, vec!["Lava".to_string(), "Hibicus".to_string()]);
 
// set rate up 6 star have 2 operator
banner.set_rate_up(6, vec!["Surtr".to_string(), "Skadi".to_string()]);
// set rate up 5 star have 3 operator
banner.set_rate_up(5, vec!["Specter".to_string(), "Ptilopsis".to_string(), "Lappland".to_string()]);
 
let (star, opname, is_up) = banner.gacha_operator();
println!("{} {} {}", is_up, star, opname);

Source

pub fn gacha_operator(&mut self) -> (u8, String, bool)

Simulate Arknights headhunt once
It have the exact same mechanic in game (or i think that have :)))) )
Mechanism:
In a single headhunt, you have the following change to get an operator:

2% to get 6 star operator
8% to get 5 star operator
50% to get 4 star operator
40% to get 3 star operator
In the first 10 headhunt in a banner, if you don’t get a 5 star or higher star operator the 10th headhunt guaranteed a 5 star operator
If for 50 headhunt, you don’t get a 6 star operator, from the 51st headhunt will increase change to get six star operator by 2% (change to get 6 star operator in the 51st headhunt is 4%, 52nd is 6%, …)
If the result is 5 star operator or 6 star operator, you will have change to get the rate up operator
50% to get 5 star rate up operator
70% to get 6 star rate up operator in Limited banner
50% to get 6 star rate up operator in Standard banner

Function returns: (star_result, operator_name, is_up)

star_result: can be any number in range 3..=6
operator_name: name of the operator
is_up: the operator is rate up or not

§Example

use prts::Banner;
 
let mut banner = Banner::from_file("./data/operators.toml".to_string());
let (star, opname, is_up) = banner.gacha_operator();
println!("{} {} {}", is_up, star, opname);

§Panics

May Panik if operator pool or operator rate up is not set

Source

pub fn gacha_10_times(&mut self) -> Vec<(u8, String, bool)>

Simulate Arknights headhunt 10 times

§Example

use prts::Banner;
 
let mut banner = Banner::from_file("./data/operators.toml".to_string());
let res = banner.gacha_10_times();
for (star, name, is_up) in &res {
    println!("{} {} {}", is_up, star, name);
}

§Panics

May Panik if operator pool or operator rate up is not set

Source

pub fn set_dokutah_info( &mut self, non_six_star_count: u8, guarantee_five_star: i8, )

set non_six_star_count and guarantee_five_star of Banner can be useful when have many doctor, but need to create only 1 banner

§Example

use prts::Banner;
 
let mut banner = Banner::from_file("./data/operators.toml".to_string());
let res = banner.gacha_10_times();
for (star, name, is_up) in &res {
    println!("{} {} {}", is_up, star, name);
}
let old_dokutah_infor = (banner.rarity.non_six_star_count, banner.rarity.guarantee_five_star);
banner.set_dokutah_info(90, 0);
let res = banner.gacha_10_times();
for (star, name, is_up) in &res {
    println!("{} {} {}", is_up, star, name);
}
