Struct Address 

pub struct Address(/* private fields */);

Canonical relative path; invariants enforced at the sole constructor.

Implementations

impl Address

pub fn parse(raw: &str) -> Result<Self, AxError>

Sole constructor; crate::schema restates this grammar as one pattern for clients. Rejects: empty input, absolute paths, backslash, : (drive letters and NTFS streams alike), control characters, empty segments, ./.., and a segment ending in a dot or whitespace. Fail-closed: not canonical is E_INVALID_ARGS.

pub fn is_within(&self, prefix: &Address) -> bool

WriteDomain primitive: true iff self equals prefix or lies under it on a segment boundary. Byte-wise, reflexive, transitive.

pub fn is_reserved(&self) -> bool

C17 primitive: true iff any segment names protected metadata (PROTECTED_METADATA), compared without ASCII case, because Windows resolves .SPRAWLING to the same directory and this predicate guards the directory rather than the string. ASCII folding is the whole of it: the names are ASCII, so a Unicode case table would add a second, version-dependent authority on the same question.

Any segment rather than the first: a building’s own rules sit at <building>/.sprawling/, and a run whose write domain is its building must not reach them. Widening this predicate can only refuse more, which is the direction a fail-closed check may move in without a second authority to check it against (crates/kernel/spec/Address.lean §8-73).

pub fn as_str(&self) -> &str

pub fn name(&self) -> &str

What this place or resident is called: the last segment, which is the word a person typed when they made it. The whole address reads like a path; the last segment reads like somebody. The grammar admits no empty segment, so there is always one to give.
