Trait CtzEmitter 

Source 
pub trait CtzEmitter<T0, T1> {
    // Required method
    fn ctz(&mut self, rd: T0, rs1: T1);
}
Expand description

Count trailing zero bits

This instruction counts the number of 0’s before the first 1, starting at the least-significant bit (i.e., 0) and progressing to the most-significant bit (i.e., XLEN-1). Accordingly, if the input is 0, the output is XLEN, and if the least-significant bit of the input is a 1, the output is 0.

§Forms

Assembly: ctz xd, xs1 Rust: ctz(rd, rs1)

§Arguments

  • rd — Destination register.
  • rs1 — Source register.

Required Methods§

Source

fn ctz(&mut self, rd: T0, rs1: T1)

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
