Enum JsonIpldError 

#[non_exhaustive]
pub enum JsonIpldError {
    DepthExceeded {
        cap: usize,
    },
    UnsignedOverflow {
        value: String,
    },
    UnsupportedNumber {
        value: String,
    },
}

Failure modes for json_to_ipld.

Deliberately coarse-grained; each variant carries enough detail for a caller to render a user-facing error without string-parsing the Display output.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

DepthExceeded

The input exceeded IPLD_MAX_DEPTH levels of nesting.

Fields

cap: usize

The cap that was exceeded; always equals IPLD_MAX_DEPTH.

UnsignedOverflow

A JSON Number was an unsigned integer greater than i64::MAX. Such values cannot round-trip through Ipld::Integer (which is i128 but DAG-CBOR encodes only i64 / u64) without ambiguity; the old “demote to Ipld::Float” path silently lost precision above 2^53.

Fields

value: String

The rejected value, rendered as it appeared in the input.

UnsupportedNumber

A JSON Number was neither an i64, a u64, nor a finite f64. In practice this cannot happen from serde_json today (the Number variants exhaust the space) but is kept as a defensive catch-all.

Fields

value: String

The rejected value, rendered as it appeared in the input.

Trait Implementations

impl Debug for JsonIpldError

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

Formats the value using the given formatter.

impl Display for JsonIpldError

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

Formats the value using the given formatter.

impl Error for JsonIpldError

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.
