Method value

arrow-array/src/array/map_array.rs:218–222

Returns ith value of this map array. This is a [`StructArray`] containing two fields Note: This method does not check for nulls and the value is arbitrary (but still well-defined) if [`is_null`](Self::is_null) returns true for the index. # Panics Panics if index `i` is out of bounds

(&self, i: usize)

    /// # Panics
    /// Panics if index `i` is out of bounds
    pub fn value(&self, i: usize) -> StructArray {
        let end = self.value_offsets()[i + 1] as usize;
        let start = self.value_offsets()[i] as usize;
        self.entries.slice(start, end - start)
    }

    /// Returns the offset values in the offsets buffer
