Enum AccessLevel 

pub enum AccessLevel {
    None,
    Read,
    Comment,
    Write,
    Admin,
}

Access level enum for files

The variant order IS the ordering (None < Read < Comment < Write < Admin), so Ord lets callers cap one level by another — e.g. a share manager may not grant more than they hold.

Variants

None

Read

Comment

Write

Admin

Implementations

impl AccessLevel

pub fn as_str(&self) -> &'static str

pub fn from_str_name(s: &str) -> Option<Self>

Parse the wire/attribute name produced by AccessLevel::as_str, for call sites that receive a level as an untyped string (the ABAC object attribute bag). Unknown names yield None so a caller denies rather than guessing.

pub fn from_perm_char(c: char) -> Self

Convert a permission char (‘R’, ‘C’, ‘W’, ‘A’) to an access level.

The single converter for the permission CHAR(1) vocabulary used by share_entries, file_user_data.access_level and ref rows. 'A' is a distinct level, not a synonym for write: it additionally confers share management. Unknown chars fall back to Read — fail-safe for a corrupt row, which the adapter logs.

pub fn to_perm_char(self) -> Option<char>

Map an access level back to its single-char wire form.

Injective inverse of AccessLevel::from_perm_char. None has no char — the caller should clear the stored value rather than write a stale 'R'.

pub fn to_scope_char(self) -> Option<char>

Map an access level to the char used inside a token scope (file:{id}:{R|C|W}).

Deliberately lossy at the top: Admin caps to 'W'. share_access refuses every scoped caller, so admin inside a scope would be unusable, and emitting it risks a parser elsewhere reading it as authority.

None has no char, mirroring AccessLevel::to_perm_char: a scope is a grant, so “no access” must not silently become a read scope. Callers already hold >= Read, making the None arm a compile-time reminder rather than a live path.

pub fn can_read(self) -> bool

May read the resource.

pub fn can_comment(self) -> bool

May comment on the resource.

pub fn can_write(self) -> bool

May modify the resource. True for Admin too — use ordering, never == Write.

pub fn can_manage_shares(self) -> bool

May manage the resource’s share set (grant, revoke, mint share links).
