# Function core::arch::arm::__ISB[−][src]

    pub unsafe fn __ISB()

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on ARM and target feature `mclass` only.

Instruction Synchronization Barrier

Instruction Synchronization Barrier flushes the pipeline in the processor, so that all instructions following the ISB are fetched from cache or memory, after the instruction has been completed.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
