    pub columns: Vec<String>,
    pub column_types: Vec<LogicalType>,
    pub rows: Vec<Vec<Value>>,
}

Result of a query execution.

Fields

columns: Vec<String>

column_types: Vec<LogicalType>

Column types (used for distinguishing Node/Edge IDs from regular integers).

rows: Vec<Vec<Value>>

Result rows.

Implementations

impl QueryResult

pub fn new(columns: Vec<String>) -> Self

Creates a new empty query result.

pub fn with_types(columns: Vec<String>, column_types: Vec<LogicalType>) -> Self

Creates a new empty query result with column types.

pub fn row_count(&self) -> usize

Returns the number of rows.

pub fn column_count(&self) -> usize

Returns the number of columns.

pub fn is_empty(&self) -> bool

Returns true if the result is empty.

pub fn scalar<T: FromValue>(&self) -> Result<T>

Gets a single scalar value from the result.

Errors

Returns an error if the result doesn’t have exactly one row and one column.

pub fn iter(&self) -> impl Iterator<Item = &Vec<Value>>

Returns an iterator over the rows.
