partition_identity

Struct PartitionID

Source 
pub struct PartitionID {
    pub variant: PartitionSource,
    pub id: String,
}
Expand description

Describes a partition identity.

A device path may be recovered from this.

§Notes

This is a struct instead of an enum to make access to the id string easier for situations where the variant does not need to be checked.

Fields§

§variant: PartitionSource§id: String

Implementations§

Source§

Source

pub fn new(variant: PartitionSource, id: String) -> Self

Construct a new PartitionID as the given source.

Source
