Struct ExtensionSet 

pub struct ExtensionSet { /* private fields */ }

VFS extension protocol versions supported by a backend.

Implementations

impl ExtensionSet

pub fn versions(&self, name: &str) -> Option<&[u16]>

Returns all supported versions for name, in ascending order.

pub fn supports(&self, name: &str, version: u16) -> bool

Returns whether the exact extension version is supported.

pub fn maximum_common_version( &self, name: &str, supported: &[u16], ) -> Option<u16>

Returns the highest version supported by both the backend and caller.
