Enum ToolError 

#[non_exhaustive]
pub enum ToolError {
    NoTool,
    NotUsable,
    Obstacle,
    NothingSelected,
    SpaceHandle(HandleError),
    Internal(String),
}

Ways that a tool can fail.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoTool

There was no tool to use (empty inventory slot, nonexistent slot, nonexistent inventory…).

NotUsable

The tool cannot currently be used or does not apply to the target.

Obstacle

Cannot place a block or similar because there’s a block occupying the space.

NothingSelected

The tool requires a target cube and none was present.

SpaceHandle(HandleError)

The space to be operated on could not be accessed.

Internal(String)

An error occurred while executing the effects of the tool. TODO: Improve this along with Transaction error types.

Implementations

impl ToolError

pub fn fluff(&self) -> impl Iterator<Item = Fluff> + use<>

Return Fluff to accompany this error.

TODO: This should have spatial information (located at the cursor target or the character’s “hand” or other).

Trait Implementations

impl Clone for ToolError

fn clone(&self) -> ToolError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ToolError

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

Formats the value using the given formatter.

impl Display for ToolError

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

Formats the value using the given formatter.

impl Error for ToolError

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<HandleError> for ToolError

fn from(value: HandleError) -> Self

Converts to this type from the input type.

impl Hash for ToolError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ToolError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
