Enum AccessMode 

pub enum AccessMode {
    Read,
    Write,
    Deny,
}

Filesystem access requested or granted for a policy entry.

This type intentionally does not implement Ord. Use Self::most_restrictive when combining access modes; declaration order is not an authorization rule.

Variants

Read

Permit reads but not modifications.

Write

Permit reads and modifications.

Deny

Permit neither reads nor modifications.

Implementations

impl AccessMode

pub const fn can_read(self) -> bool

Returns whether this mode permits a read.

pub const fn can_write(self) -> bool

Returns whether this mode permits a modification.

pub const fn most_restrictive(self, other: Self) -> Self

Returns the more restrictive capability for two conflicting grants.

The order is Deny over Read over Write. Explicit profile replacement is a separate operation owned by the config resolver.

pub const fn permits(self, requested: Self) -> bool

Returns whether this grant satisfies a requested access mode.
