Struct AsciiWriter

pub struct AsciiWriter<T: Write + Seek> { /* private fields */ }

PointWriterFormatting implementation for Ascii files

Implementations

impl AsciiWriter<BufWriter<File>>

pub fn from_path<P: AsRef<Path>>(path: P, format: &str) -> Result<Self>

Creates a new AsciiWriter by opening the file at the given path. The format string slice coordinates the interpretation of each column. This functions just wraps a BufWriter around a File and uses AsciiWriter::from_write. For more information see AsciiWriter::from_write.

Examples

use std::path::Path;
use anyhow::Result;
use pasture_io::ascii::AsciiWriter;
fn main() -> Result<()> {
    let path = Path::new("output.txt");
    let writer = AsciiWriter::from_path(path, "xyzie")?;
    Ok(())
}

Errors

If path cannot be created or overwritten, an error is returned.

If format contains unrecoginzed literals, an error is returned.

impl<T: Write + Seek> AsciiWriter<T>

pub fn from_write(write: T, format: &str) -> Result<Self>

Creates a new AsciiWriter from the given write. The format string slice coordinates the interpretation of each column. The following literals can be interpreted from AsciiWriter:

• s → skip this column
• x → x coordinate
• y → y coordinate
• z → z coordinate
• i → intensity
• r → ReturnNumber
• n → number of returns of given pulse
• c → classification
• t → gps time
• u → user data
• p → point source ID
• R → red channel of RGB color
• G → green channel of RGB color
• B → blue channel of RGB color
• e → edge of flight line flag
• d → direction of scan flag
• a → scan angle rank
• I → NIR channel

Examples

use std::io::{BufWriter};
use std::fs::File;
use anyhow::Result;
use pasture_io::ascii::AsciiWriter;
fn main() -> Result<()> {
    let write = BufWriter::new(File::create("output.txt")?);
    let writer = AsciiWriter::from_write(write, "xyzi")?;
    Ok(())
}

Errors

If the given Write cannot write, an error is returned.

If format contains unrecoginzed literals, an error is returned.

Trait Implementations

impl<T: Write + Seek> PointWriter for AsciiWriter<T>

fn write<'a, B: BorrowedBuffer<'a>>(&mut self, points: &'a B) -> Result<()>

Write the points in the given PointBuffer to the associated PointWriter.

fn flush(&mut self) -> Result<()>

Flush this PointWriter, ensuring that all points are written to their destination and that all required metadata is written as well

fn get_default_point_layout(&self) -> &PointLayout

Returns the default PointLayout of the associated PointWriter
