CapToken

Struct CapToken 

Source
pub struct CapToken { /* private fields */ }
Expand description

An unforgeable capability token.

Capability tokens are the sole mechanism for accessing RVM resources. They are created by the kernel and cannot be forged by partitions.

Implementations§

Source§

impl CapToken

Source

pub const fn new( id: u64, cap_type: CapType, rights: CapRights, epoch: u32, ) -> Self

Create a new capability token.

Source

pub const fn id(self) -> u64

Return the capability identifier.

Source

pub const fn cap_type(self) -> CapType

Return the capability type.

Source

pub const fn rights(self) -> CapRights

Return the access rights.

Source

pub const fn epoch(self) -> u32

Return the epoch counter.

Source

pub const fn has_rights(self, required: CapRights) -> bool

Check whether this token carries the given rights.

Source

pub const fn truncated_hash(self) -> u32

Return a truncated 32-bit hash for witness record embedding.

This is NOT the full capability – it is a truncated hash used for identification without leaking the full token contents.
