Enum WorkspaceEditError 

pub enum WorkspaceEditError {
    WorkspaceNotInitialised {
        path: PathBuf,
    },
    InvalidToml {
        path: PathBuf,
        message: String,

        pattern: String,
        stored: Vec<String>,

Errors returned by the writer.

The idempotency cases (RuleAlreadyExists, RuleNotFound, CrossLinkAlreadyGranted, CrossLinkNotGranted) live on WorkspaceEditWarning rather than here — re-grant / re-revoke / re-add / re-remove return success-with-warning rather than refusing, letting CLI scripts and MCP agents retry safely without branching on prior state. CrossLinkConflict stays an error because it’s a real semantic conflict (wildcard vs. specific list), not an idempotency case.

Variants

WorkspaceNotInitialised

.memstead/workspace.toml missing or unreadable. The workspace must be initialised before the CLI can edit its config.

Fields

path: PathBuf

InvalidToml

Existing file failed to parse as TOML.

Fields

path: PathBuf

message: String

BeforePatternNotFound

add_create_rule with --before <p> where <p> isn’t an existing pattern in the section.

Fields

section: &'static str

pattern: String

CrossLinkConflict

grant_cross_link with * against an existing specific list, or with a specific target against an existing *. Operators pick a single shape per from-mem.

Fields

from: String

message: String

RuleExistsSchemasDiffer

add_create_rule called for a pattern that already exists but with a different schema set. Refused rather than silently no-op’d: changing a pattern’s schema pins is a security-relevant policy change, so it must be explicit (revoke the rule, then re-add with the new schemas) — never a silent success echoing a change that did not land. The genuine no-op (identical schemas) stays WorkspaceEditWarning::RuleAlreadyPresent.

Fields

section: &'static str

pattern: String

stored: Vec<String>

requested: Vec<String>

Io

IO failure writing the file back.

Fields

path: PathBuf

source: Error

Implementations

impl WorkspaceEditError

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

Stable symbolic code used by the CLI exit envelope.

Trait Implementations

impl Debug for WorkspaceEditError

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

Formats the value using the given formatter.

impl Display for WorkspaceEditError

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

Formats the value using the given formatter.

impl Error for WorkspaceEditError

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>)
