Source
pub struct RelationDeserializer<'a> { /* private fields */ }
Expand description

Extract typed values from a parsed JSON array row.

Implementations§

Source§

impl<'a> RelationDeserializer<'a>

Source

pub fn new(values: &'a [Value]) -> Self

Create a deserializer over a slice of JSON values.

Source

pub fn get<T: DeserializeOwned>(&self, index: usize) -> Result<T, DbCoreError>

Extract a typed value at the given index.

§Errors

Returns DbCoreError::RowMapping when index is out of range or the value cannot be deserialized to T.

Source

pub fn len(&self) -> usize

Number of values in this row.

Source

pub fn is_empty(&self) -> bool

Whether this row has no values.
