Enum DiscoverError 

pub enum DiscoverError {
    Io(Error),
    CircularInclude(String),
    InvalidKey(String),
    NonNativeKey(String),
}

Errors from file discovery.

Variants

Io(Error)

File I/O error during discovery.

CircularInclude(String)

Circular INCLUDE dependency detected.

InvalidKey(String)

A native discovery key is not root-relative (contains a .. segment). native_module_path treats .. literally, so letting one through would mint a bogus module (../x.brink → story::..::x) — save-key-identity-critical (issue #1288 review note (a)). Every current SourceTree (RealFs, GitRev, InMemory) already produces root-relative, ..-free keys; this guards against a future implementation that doesn’t.

NonNativeKey(String)

A key discover_native was handed does not have the .brink extension. discover_native must only ever see native source (issue #1371): tree is a &dyn SourceTree, and nothing at the type level stops a caller from handing it an implementation scoped wider than .brink alone — e.g. brink_source_tree::InMemory, the tree brink-web’s compile() builds (.ink-keyed) and hands to brink_environment::Project::load, not to native discovery — which would let .ink text be parsed as brink source. Checked (like InvalidKey) before any file is loaded, so a violation rejects the whole discovery, not just the offending key.

Trait Implementations

impl Debug for DiscoverError

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

Formats the value using the given formatter.

impl Display for DiscoverError

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

Formats the value using the given formatter.

impl Error for DiscoverError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for DiscoverError

fn from(source: Error) -> Self

Converts to this type from the input type.
