Struct geos::ContextHandle [−][src]
pub struct ContextHandle<'a> { /* fields omitted */ }
Implementations
Creates a new ContextHandle
.
Example
use geos::ContextHandle; let context_handle = ContextHandle::init().expect("invalid init");
Returns the last error encountered.
Please note that calling this function will remove the current last error!
use geos::ContextHandle; let context_handle = ContextHandle::init().expect("invalid init"); // make some functions calls... if let Some(last_error) = context_handle.get_last_error() { println!("We have an error: {}", last_error); } else { println!("No error occurred!"); }
Returns the last notification encountered.
Please note that calling this function will remove the current last notification!
use geos::ContextHandle; let context_handle = ContextHandle::init().expect("invalid init"); // make some functions calls... if let Some(last_notif) = context_handle.get_last_notification() { println!("We have a notification: {}", last_notif); } else { println!("No notifications!"); }
Gets WKB output dimensions.
Example
use geos::{ContextHandle, OutputDimension}; let mut context_handle = ContextHandle::init().expect("invalid init"); context_handle.set_wkb_output_dimensions(OutputDimension::TwoD); assert_eq!(context_handle.get_wkb_output_dimensions(), Ok(OutputDimension::TwoD));
pub fn set_wkb_output_dimensions(
&mut self,
dimensions: OutputDimension
) -> GResult<OutputDimension>
[src]
pub fn set_wkb_output_dimensions(
&mut self,
dimensions: OutputDimension
) -> GResult<OutputDimension>
[src]Sets WKB output dimensions.
Example
use geos::{ContextHandle, OutputDimension}; let mut context_handle = ContextHandle::init().expect("invalid init"); context_handle.set_wkb_output_dimensions(OutputDimension::TwoD); assert_eq!(context_handle.get_wkb_output_dimensions(), Ok(OutputDimension::TwoD));
Gets WKB byte order.
Example
use geos::{ContextHandle, ByteOrder}; let mut context_handle = ContextHandle::init().expect("invalid init"); context_handle.set_wkb_byte_order(ByteOrder::LittleEndian); assert!(context_handle.get_wkb_byte_order() == ByteOrder::LittleEndian);
Sets WKB byte order.
Example
use geos::{ContextHandle, ByteOrder}; let mut context_handle = ContextHandle::init().expect("invalid init"); context_handle.set_wkb_byte_order(ByteOrder::LittleEndian); assert!(context_handle.get_wkb_byte_order() == ByteOrder::LittleEndian);
