Struct cassandra_cpp::CassResult[−][src]

pub struct CassResult(_);

The result of a query. A result object is read-only and is thread-safe to read or iterate over concurrently, since we do not bind any setters (e.g., set_metadata).

Implementations

impl CassResult[src]

pub fn row_count(&self) -> u64[src]

Gets the number of rows for the specified result.

pub fn column_count(&self) -> u64[src]

Gets the number of columns per row for the specified result.

pub fn column_name(&self, index: usize) -> Result<&str>[src]

Gets the column name at index for the specified result.

pub fn column_type(&self, index: usize) -> ValueType[src]

Gets the column type at index for the specified result.

pub fn column_data_type(&self, index: usize) -> ConstDataType[src]

Gets the column datatype at index for the specified result.

pub fn first_row(&self) -> Option<Row<'_>>[src]

Gets the first row of the result.

pub fn has_more_pages(&self) -> bool[src]

Returns true if there are more pages.

pub fn paging_state_token(&self) -> Result<Option<Vec<u8>>>[src]

Gets the statement’s paging state. This can be used to get the next page of data in a multi-page query, by using set_paging_state_token.

Returns:

  • Ok(None) if there are no more pages, and thus no paging state token.
  • `Ok(Some(Vec)) if there are more pages, and a paging state token.
  • Err(_) if there was an error getting the paging state token.

pub fn iter(&self) -> ResultIterator<'_>[src]

Creates a new iterator for the specified result. This can be used to iterate over rows in the result.
