Errors that can occur during schema encoding/decoding

This error type covers all failure modes in the schema encoding pipeline: parsing, binary packing/unpacking, compression, and framing.

Examples

use base_d::{decode_schema, SchemaError};

let result = decode_schema("invalid", false);
match result {
    Err(SchemaError::InvalidFrame(msg)) => {
        println!("Frame error: {}", msg);
    }
    Err(SchemaError::InvalidCharacter(msg)) => {
        println!("Character error: {}", msg);
    }
    _ => {}
}

Trait Implementations

impl Debug for SchemaError

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

Formats the value using the given formatter.

impl Display for SchemaError

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

Formats the value using the given formatter.

impl Error for SchemaError

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 SchemaError

fn eq(&self, other: &SchemaError) -> 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.
