Enum ElementSize 

pub enum ElementSize {
    B,
    H,
    S,
    D,
}

The element size of an AArch64 vector lane access (V0.S[0]).

Variants

B

Byte (.B) — 16 lanes.

H

Half-word (.H) — 8 lanes.

S

Single-word (.S) — 4 lanes.

D

Double-word (.D) — 2 lanes.

Implementations

impl ElementSize

pub fn from_lower(s: &str) -> Option<Self>

Parse a lane-size suffix. Input must already be lowercase.

pub fn lane_count(self) -> u8

Number of lanes of this size in a 128-bit vector register.

pub fn imm5(self, index: u8) -> u32

The imm5 lane selector shared by INS, UMOV, SMOV and DUP.

The size is encoded in the position of the lowest set bit, with the index sitting above it — so imm5 names both at once.

pub fn imm4(self, index: u8) -> u32

The imm4 source-lane selector used by INS (element).
