Enum BlockJsonStructureError 

pub enum BlockJsonStructureError {
    IdNotFound,
    BlockIsNoMapping,
    MissingMandatoryAttr(&'static str),
    AttrWrongType {
        attr: &'static str,
        correct_type: &'static str,
    },
}

General block parsing failed because of the json structure, this is not about attributes.

Variants

IdNotFound

The requested block Id wasn’t found in the target’s json mapping blocks

This should rarely occur as multiple program parts only request blocks that were previously found in the file by e. g. iterating over all block Ids

BlockIsNoMapping

The found block data (for the requested Id) is not a json mapping ({ ... }). This should never happen in a valid file.

MissingMandatoryAttr(&'static str)

Mapping is missing a needed key-value-pair, like inputs or fields.

Regardless of the block’s kind or opcode, some attributes need to be present. Examples of such attributes are opcode or inputs. For procedures the mutation key has to be present additionally.

AttrWrongType

A block property is of invalid form, this is not about attributes like in crate::attrs.

inputs, fields and mutation need to be – if present – json mappings from attribute names to their values. An opcode should be a string. This error indicates that one of those expectations was violated.

Fields

attr: &'static str

correct_type: &'static str

Trait Implementations

impl Clone for BlockJsonStructureError

fn clone(&self) -> BlockJsonStructureError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlockJsonStructureError

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

Formats the value using the given formatter.

impl Display for BlockJsonStructureError

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

Formats the value using the given formatter.

impl Error for BlockJsonStructureError

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<'a> From<BlockJsonStructureError> for BlockKindError<'a>

fn from(source: BlockJsonStructureError) -> BlockKindError<'a>

Converts to this type from the input type.

impl PartialEq for BlockJsonStructureError

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

Equality operator ==.

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

Inequality operator !=.
