Enum FrontendError 

pub enum FrontendError {
    Parse(String),
    ParseDiagnostics(Vec<ParseDiagnostic>),
    UnsupportedVersion(String),
    ImportError {
        path: String,
        reason: String,
    },
    ContractNotFound(String),
}

Errors emitted by the frontend while parsing Solidity code.

Variants

Parse(String)

Parsing failed; the contained message aggregates all diagnostics.

ParseDiagnostics(Vec<ParseDiagnostic>)

Parsing failed; structured per-diagnostic form (preferred). Preserves each diagnostic’s byte range for precise tooling output.

UnsupportedVersion(String)

Invalid Solidity version pragma

ImportError

Import resolution failed

Fields

path: String

reason: String

ContractNotFound(String)

Contract not found in source

Implementations

impl FrontendError

pub fn parse_at(line: usize, column: usize, message: impl Into<String>) -> Self

Create a parse error with location info

pub fn import_error(path: impl Into<String>, reason: impl Into<String>) -> Self

Create an import error

pub fn is_recoverable(&self) -> bool

Check if this is a recoverable error

Trait Implementations

impl Debug for FrontendError

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

Formats the value using the given formatter.

impl Display for FrontendError

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

Formats the value using the given formatter.

impl Error for FrontendError

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<FrontendError> for SolidityError

fn from(source: FrontendError) -> Self

Converts to this type from the input type.
