Enum ParseError 

pub enum ParseError {
    Io(Error),
    Parse(String),
    InvalidTailSection {
        section: String,
        message: String,
        line_number: Option<usize>,
    },
    GaussianSyntaxError {
        section: String,
        details: String,
        line_number: Option<usize>,
    },
}

Error type for parsing operations.

Parsing can fail due to:

• File I/O errors (missing files, permission issues)
• Format errors (malformed input, invalid values)
• Unsupported file formats
• Invalid tail section content
• Gaussian syntax errors

Variants

Io(Error)

I/O error when reading files

Parse(String)

Parse error with descriptive message

InvalidTailSection

Invalid tail section content with detailed context

Fields

section: String

Name of the tail section (e.g., “TAIL_a”, “TAIL_b”)

message: String

Descriptive error message

line_number: Option<usize>

Optional line number where the error occurred

GaussianSyntaxError

Gaussian syntax error with detailed context

Fields

section: String

Name of the section where the error occurred

details: String

Detailed error information

line_number: Option<usize>

Optional line number where the error occurred

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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<Error> for ParseError

fn from(source: Error) -> Self

Converts to this type from the input type.
