Struct IdMappings 

pub struct IdMappings {
    pub uid_map: Vec<IdMapEntry>,
    pub gid_map: Vec<IdMapEntry>,
    /* private fields */

Fields

uid_map: Vec<IdMapEntry>

gid_map: Vec<IdMapEntry>

Implementations

impl IdMappings

pub fn new(uid_map: Vec<IdMapEntry>, gid_map: Vec<IdMapEntry>) -> Self

pub fn find_mapping(&self, id: u32, direct: bool, uid: bool) -> u32

Finds the mapped ID based on the provided mappings.

If no mapping is found, returns the original ID.

• direct is true: Reverse mapping (Host -> Container).
• direct is false: Forward mapping (Container -> Host).

pub fn get_uid(&self, container_id: u32) -> u32

Gets the host UID from a container UID (Forward mapping).

pub fn get_gid(&self, container_id: u32) -> u32

Gets the host GID from a container GID (Forward mapping).

Trait Implementations

impl Clone for IdMappings

fn clone(&self) -> IdMappings

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IdMappings

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for IdMappings

fn default() -> IdMappings

Returns the “default value” for a type.

impl FromStr for IdMappings

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for IdMappings

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for IdMappings

fn eq(&self, other: &IdMappings) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
