Struct Feature

Source
pub struct Feature(pub u32);
Expand description

A piece of optional data stored in a perf.data file. Its data is contained in a “feature section” at the end of the file.

For each used feature, a bit is set in the feature flags in the file header. The feature sections are stored just after the file’s data section; there’s one section for each enabled feature, ordered from low feature bit to high feature bit.
