Struct JsonError 

pub struct JsonError {

    pub code: String,
    pub detail: String,
    pub pos: usize,
    pub row: usize,
    pub col: usize,
    pub src: String,
    pub hint: String,
    pub tag: String,
    pub full_source: String,
    pub len: usize,
    pub rule: String,
    pub rule_stack: Vec<String>,
    pub token: ErrorToken,
    pub expected: Vec<String>,
    pub plugins: Vec<String>,
    pub recovered: Option<RecoveredAt>,
    /* private fields */
}

The error a failed parse produces, re-exported so callers need not depend on the engine crate directly. Mirrors the TypeScript export { TabnasError as JsonError }.

Fields

code: String

detail: String

pos: usize

row: usize

col: usize

src: String

hint: String

tag: String

full_source: String

len: usize

rule: String

rule_stack: Vec<String>

token: ErrorToken

expected: Vec<String>

plugins: Vec<String>

recovered: Option<RecoveredAt>

Recovery metadata is intentionally not part of the stable serialized diagnostic schema, matching the canonical implementations.

Implementations

impl TabnasError

pub fn new( code: impl Into<String>, src: impl Into<String>, full_source: impl Into<String>, pos: usize, row: usize, col: usize, ) -> TabnasError

pub fn attach_context( &mut self, rule: &str, rule_state: &str, rule_stack: Vec<String>, token: Option<&Token>, expected: Vec<String>, )

Trait Implementations

impl Clone for TabnasError

fn clone(&self) -> TabnasError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TabnasError

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

Formats the value using the given formatter.

impl Display for TabnasError

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

Formats the value using the given formatter.

impl Error for TabnasError

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<ActionError> for TabnasError

fn from(action_error: ActionError) -> TabnasError

Converts to this type from the input type.

impl PartialEq for TabnasError

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for TabnasError

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
