Struct netcdf::FileMem

pub struct FileMem<'buffer>(/* private fields */);

Available on crate feature has-mmap only.

The memory mapped file is kept in this structure to extend the lifetime of the buffer.

Access a File through the Deref trait,

let buffer = &[0, 42, 1, 2];
let file = &netcdf::open_mem(None, buffer)?;

let variables = file.variables();

Methods from Deref<Target = File>

pub fn path(&self) -> Result<PathBuf>

path used to open/create the file

#Errors

Netcdf layer could fail, or the resulting path could contain an invalid UTF8 sequence

pub fn root(&self) -> Option<Group<'_>>

Main entrypoint for interacting with the netcdf file.

pub fn variable<'f>(&'f self, name: &str) -> Option<Variable<'f>>

Get a variable from the group

pub fn variables(&self) -> impl Iterator<Item = Variable<'_>>

Iterate over all variables in a group

pub fn attribute<'f>(&'f self, name: &str) -> Option<Attribute<'f>>

Get a single attribute

pub fn attributes(&self) -> impl Iterator<Item = Attribute<'_>>

Get all attributes in the root group

pub fn dimension<'f>(&self, name: &str) -> Option<Dimension<'f>>

Get a single dimension

pub fn dimensions(&self) -> impl Iterator<Item = Dimension<'_>>

Iterator over all dimensions in the root group

pub fn group<'f>(&'f self, name: &str) -> Result<Option<Group<'f>>>

Get a group

Errors

Not a netCDF-4 file

pub fn groups(&self) -> Result<impl Iterator<Item = Group<'_>>>

Iterator over all subgroups in the root group

Errors

Not a netCDF-4 file

pub fn types(&self) -> Result<impl Iterator<Item = VariableType>>

Return all types in the root group

Trait Implementations

impl<'a> Deref for FileMem<'a>

type Target = File

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
