Enum WrapError 

pub enum WrapError {
    InvalidColumnWidth(usize),
    InputTooLarge(usize, usize),
}

Comprehensive error types for wrap-ansi operations.

This enum provides detailed error information for various failure modes that can occur during text wrapping operations.

Examples

use wrap_ansi::{wrap_ansi_checked, WrapError};

// Handle invalid column width
match wrap_ansi_checked("test", 0, None) {
    Err(WrapError::InvalidColumnWidth(width)) => {
        println!("Column width {} is invalid, must be > 0", width);
    }
    Ok(result) => println!("Wrapped: {}", result),
    _ => {}
}

// Handle input size limits
let huge_input = "x".repeat(20_000_000);
match wrap_ansi_checked(&huge_input, 80, None) {
    Err(WrapError::InputTooLarge(size, max_size)) => {
        println!("Input {} bytes exceeds limit of {} bytes", size, max_size);
    }
    Ok(result) => println!("Wrapped successfully"),
    _ => {}
}

Variants

InvalidColumnWidth(usize)

Column width must be greater than 0.

This error occurs when attempting to wrap text with a column width of 0, which would be impossible to satisfy.

InputTooLarge(usize, usize)

Input string is too large to process safely.

This error provides protection against potential DoS attacks by limiting the maximum input size that can be processed.

Trait Implementations

impl Debug for WrapError

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

Formats the value using the given formatter.

impl Display for WrapError

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

Formats the value using the given formatter.

impl Error for WrapError

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 PartialEq for WrapError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
