Struct SyntaxError 

pub struct SyntaxError {
    pub message: String,
    pub line: Option<usize>,
    pub snippet: Option<String>,
}

A structured syntax error with optional line number and source context.

Callers that match on TemplateError::Syntax can inspect line and snippet programmatically instead of parsing the error message string.

Fields

message: String

The error message (without location prefix).

line: Option<usize>

1-based line number where the error occurred (if known).

snippet: Option<String>

Snippet of the offending source line (if available).
