Struct agnes::frame::DataFrame
[−]
[src]
pub struct DataFrame { /* fields omitted */ }A data frame. A DataStore reference along with record-based filtering and sorting details.
Methods
impl DataFrame[src]
pub fn nrows(&self) -> usize[src]
Number of rows that pass the filter in this frame.
pub fn get_field_type(&self, ident: &FieldIdent) -> Option<FieldType>[src]
Get the field type of a particular field in the underlying DataStore.
pub fn has_field(&self, s: &FieldIdent) -> bool[src]
Returns true if this DataFrame contains this field.
