impl MetadataVersion
[src]pub const V5: Self
[src]
pub const V5: Self
[src]= 1.0.0 (July 2020. Backwards compatible with V4 (V5 readers can read V4 metadata and IPC messages). Implementations are recommended to provide a V4 compatibility mode with V5 format changes disabled.
Incompatible changes between V4 and V5:
- Union buffer layout has changed. In V5, Unions don’t have a validity bitmap buffer.

pub fn variant_name(self) -> Option<&'static str>
[src]
pub fn variant_name(self) -> Option<&'static str>
[src]Returns the variant’s name or “” if unknown.
