Struct FaceSyntaxError 

pub struct FaceSyntaxError {
    pub message: String,
    pub location: Option<SyntaxLocation>,
}

Why a declaration could not be parsed, and where when that is known. 声明为何解析不了；位置已知时一并给出。

Fields

message: String

Human-readable reason. 人类可读的原因。

location: Option<SyntaxLocation>

Where parsing failed; None when the failure is about the file as a whole. 解析失败的位置；失败针对整个文件时为 None。

impl Error for FaceSyntaxError

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
