Struct SubordinateInfo

Source

pub(crate) struct SubordinateInfo {
    pub uid: u32,
    pub gid: u32,
    pub subuid: u32,
    pub subgid: u32,
}

Expand description

Represents a single (subuid,subgid) pair for a user and their group.

In practice there are usually many more subordinate ids than just one, but for oci builds we only need one. If we ever need more, we can improve this implementation.

impl SubordinateInfo

Source

pub(crate) fn for_effective_user() -> Result<SubordinateInfo, SubordinateError>
