Struct FsError 

pub struct FsError {
    pub code: &'static str,
    pub message: String,
}

Stable FS_* code for a filesystem error. Callers match on the code, so agent-facing messages stay machine-readable.

Fields

code: &'static str

One of the FS_* constants on this module’s types.

message: String

Implementations

impl FsError

pub const FS_NOT_OBSERVED: &'static str = "FS_NOT_OBSERVED"

The path was never observed through Fence::fence_read, so the session cannot prove it edits what it saw.

pub const FS_VERSION_CONFLICT: &'static str = "FS_VERSION_CONFLICT"

The file changed between the recorded observation and the write.

pub const FS_EXISTS: &'static str = "FS_EXISTS"

A guard demanded absence and the path already exists.

pub const FS_FENCE_DENIED: &'static str = "FS_FENCE_DENIED"

The fence layers refused the operation.

pub const FS_IO: &'static str = "FS_IO"

The underlying filesystem call failed.

pub fn new(code: &'static str, message: impl Into<String>) -> Self

Trait Implementations

impl Clone for FsError

impl Eq for FsError

impl Error for FsError

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 PartialEq for FsError

fn eq(&self, other: &FsError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
