Struct parquet::schema::types::ColumnPath

pub struct ColumnPath { /* private fields */ }

Represents a path in a nested schema

Implementations

impl ColumnPath

pub fn new(parts: Vec<String>) -> Self

Creates new column path from vector of field names.

pub fn string(&self) -> String

Returns string representation of this column path.

use parquet::schema::types::ColumnPath;

let path = ColumnPath::new(vec!["a".to_string(), "b".to_string(), "c".to_string()]);
assert_eq!(&path.string(), "a.b.c");

pub fn append(&mut self, tail: Vec<String>)

Appends more components to end of column path.

use parquet::schema::types::ColumnPath;

let mut path = ColumnPath::new(vec!["a".to_string(), "b".to_string(), "c"
.to_string()]);
assert_eq!(&path.string(), "a.b.c");

path.append(vec!["d".to_string(), "e".to_string()]);
assert_eq!(&path.string(), "a.b.c.d.e");

pub fn parts(&self) -> &[String]

Trait Implementations

impl AsRef<[String]> for ColumnPath

fn as_ref(&self) -> &[String]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ColumnPath

fn clone(&self) -> ColumnPath

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ColumnPath

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ColumnPath

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> From<&'a str> for ColumnPath

fn from(single_path: &str) -> Self

Converts to this type from the input type.

impl From<String> for ColumnPath

fn from(single_path: String) -> Self

Converts to this type from the input type.

impl From<Vec<String>> for ColumnPath

fn from(parts: Vec<String>) -> Self

Converts to this type from the input type.

impl Hash for ColumnPath

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ColumnPath

fn eq(&self, other: &ColumnPath) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
