pub struct Case<C, E> { /* fields omitted */ }

Case holds group of when/then clauses

Methods

impl<C: 'static, E: 'static> Case<C, E>

pub fn new<T: Into<String>>(name: T) -> Self

Create a new case group

Examples

use tweak::Case;

let case = Case::<String, ()>::new("string manipulation");

pub fn when<T>(self, name: T, f: fn(_: &mut C) -> Result<bool, E>) -> Self where     T: Into<String>,

pub fn then<T>(self, name: T, f: fn(_: &mut C) -> Result<(), E>) -> Self where     T: Into<String>,

Describe an action to run if its then block returns false.

pub fn then_case<T, F>(self, name: T, f: F) -> Self where     T: Into<String>,     F: FnOnce(Case<C, E>) -> Case<C, E>,

Describe a group of then/when clauses to run if its then block returns false.

pub fn run(&self, ctx: &mut C) -> Result<bool, E>

Run all described statements.
