Struct ElementErrors 

pub(crate) struct ElementErrors {
    batch: BatchedErrors,
    refused: bool,
    class: Vec<String>,
    data: ConditionData,
}

The failures of a list read element by element (map_vecsxp_batched), folded into one error that keeps the classes and fields of the check refusals among them.

Each failure’s reason goes into a BatchedErrors, so the message has the grammar of every batched conversion: got a data frame (element 2); expected list, got numeric (elements 3, 5). A check’s refusal (SexpError::Condition) is worded by its argument_message when it has one (the type’s own words for a value refused as an argument), else by its message; any other error by SexpError::r_reason.

With no refusal among the failures the error is the batch’s SexpError::InvalidValue. With one, it is a SexpError::Condition with the batch’s message, the classes of every refusal (in the order they first occur) and their fields (the first of each name), so a handler for a check’s class catches a list of the type as it catches one value of it.

Fields

batch: BatchedErrors

refused: bool

class: Vec<String>

data: ConditionData

Implementations

impl ElementErrors

pub(crate) fn push(&mut self, index: usize, error: SexpError)

Record the failure of the element at 0-based index.

pub(crate) fn into_result<T>(self, values: T) -> Result<T, SexpError>

The values read, or the one error for every failure recorded.

Trait Implementations

impl Default for ElementErrors

fn default() -> Self

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
