Struct Backtraced 

pub struct Backtraced {
    pub message: String,
    pub help: Option<String>,
    pub note: Option<String>,
    pub code: i32,
    pub type_: String,
    pub error: bool,
    pub backtrace: Backtrace,
}

Backtraced compiler output type undefined value x –> file.leo: 2:8 = help: Initialize a variable x first.

Fields

message: String

The error message.

help: Option<String>

The error help message if it exists.

note: Option<String>

An optional contextual note (background information rather than an actionable fix).

code: i32

The error exit code.

type_: String

The characters representing the type of error.

error: bool

Is this Backtrace a warning or error?

backtrace: Backtrace

The backtrace representing where the error occurred in Leo.

Implementations

impl Backtraced

pub fn new_from_backtrace<S>( message: S, help: Option<String>, code: i32, type_: String, error: bool, backtrace: Backtrace, ) -> Self

where S: ToString,

Creates a backtraced error from a backtrace.

pub fn error(code_prefix: &str, code: i32, message: impl ToString) -> Self

Create a new error.

pub fn warning(code_prefix: &str, code: i32, message: impl ToString) -> Self

Create a new warning.

pub fn with_help(self, help: impl Display) -> Self

pub fn with_note(self, note: impl Display) -> Self

pub fn exit_code(&self) -> i32

Gets the backtraced error exit code.

pub fn error_code(&self) -> String

Gets a unique error identifier.

pub fn warning_code(&self) -> String

Gets a unique warning identifier.

pub fn is_error(&self) -> bool

Return whether this diagnostic represents an error rather than a warning.

LSP severity mapping inspects this flag rather than the rendered prefix in the diagnostic’s Display output.

Trait Implementations

impl Clone for Backtraced

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Backtraced

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

Formats the value using the given formatter.

impl Default for Backtraced

fn default() -> Self

Returns the “default value” for a type.

impl Display for Backtraced

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

Formats the value using the given formatter.

impl Error for Backtraced

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

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

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

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<Backtraced> for LeoError

fn from(source: Backtraced) -> Self

Converts to this type from the input type.

impl Hash for Backtraced

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

where __H: Hasher,

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 Backtraced

fn eq(&self, other: &Self) -> 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.
