Crate rattler_conda_types

rattler-conda-types contains data models for types commonly found within the Conda ecosystem. The library itself doesnt provide any functionality besides parsing the data types.

Re-exports

• pub use prefix_record::PrefixRecord;
• pub use version_spec::VersionSpec;

Modules

• package
  Contains models of files that are found in the info/ directory of a package.
• prefix_record
  Defines the [PrefixRecord] struct.
• version_spec
  This module contains code to work with “versionspec”. It represents the version part of crate::MatchSpec, e.g.: >=3.4,<4.0.

Structs

• Channel
  Channels are the primary source of package information.
• ChannelConfig
  The ChannelConfig describes properties that are required to resolve “simple” channel names to channel URLs.
• ChannelData
  ChannelData is an index of subdirectories and packages stored within a Channel.
• ChannelDataPackage
  Information on a single package in a channel.
• ChannelInfo
  Information about subdirectory of channel in the Conda RepoData
• ExplicitEnvironmentEntry
  A single entry in an ExplicitEnvironmentSpec. This is basically a representation of a package URL. Package URLS can also have an associated URL hash which signifies the expected hash of the package archive.
• ExplicitEnvironmentSpec
  An ExplicitEnvironmentSpec represents an explicit environment specification. Packages are represented by a URL that defines from where they should be downloaded and they are already in an explicit installation order. This ensures that there is no need to run the solver or to download repodata which makes using explicit environments for installation of environments very fast.
• GenericVirtualPackage
  A GenericVirtualPackage is a Conda package description that contains a name and a version and a build_string.
• MatchSpec
  A MatchSpec is, fundamentally, a query language for conda packages. Any of the fields that comprise a crate::PackageRecord can be used to compose a MatchSpec.
• NamelessMatchSpec
  Similar to a MatchSpec but does not include the package name. This is useful in places where the package name is already known (e.g. foo = "3.4.1 *cuda")
• NoArchType
  Noarch packages are packages that are not architecture specific and therefore only have to be built once. A NoArchType is either specific to an architecture or not. See NoArchKind for more information on the different types of noarch.
• PackageName
  A representation of a conda package name. This struct both stores the source string from which this instance was created as well as a normalized name that can be used to compare different names. The normalized name is guaranteed to be a valid conda package name.
• PackageRecord
  A single record in the Conda repodata. A single record refers to a single binary distribution of a package on a Conda channel.
• PackageRecordPatch
  Contains items that overwrite metadata values stored for a single super::PackageRecord.
• ParseArchError
  An error that can occur when parsing an arch from a string.
• ParsePlatformError
  An error that can occur when parsing a platform from a string.
• ParseVersionError
  An error that occurred during parsing of a string to a version.
• PatchInstructions
  Repodata patch instructions for a single subdirectory. See RepoDataPatch for more information.
• RepoData
  RepoData is an index of package binaries available on in a subdirectory of a Conda channel.
• RepoDataPatch
  Represents a Conda repodata patch.
• RepoDataRecord
  Information about a package from repodata. It includes a crate::PackageRecord but it also stores the source of the data (like the url and the channel).
• StrictVersion
  Version that only has equality when it is exactly the same e.g for Version 1.0.0 == 1.0 while in StrictVersion this is not equal. Useful in ranges where we are talking about equality over version ranges instead of specific version instances
• Version
  This class implements an order relation between version strings. Version strings can contain the usual alphanumeric characters (A-Za-z0-9), separated into segments by dots and underscores. Empty segments (i.e. two consecutive dots, a leading/trailing underscore) are not permitted. An optional epoch number - an integer followed by ‘!’ - can precede the actual version string (this is useful to indicate a change in the versioning scheme itself). Version comparison is case-insensitive.
• VersionWithSource
  Holds a version and the string it was created from. This is useful if you want to retain the original string the version was created from. This might be useful in cases where you have multiple strings that are represented by the same Version but you still want to be able to distinguish them.

Enums

• Arch
  Known architectures supported by Conda.
• Component
  Either a number, literal or the infinity.
• ConvertSubdirError
  An error that can occur when parsing a platform from a string.
• InvalidPackageNameError
  An error that is returned when conversion from a string to a PackageName fails.
• NamedChannelOrUrl
  Represents a channel description as either a name (e.g. conda-forge) or a base url.
• NoArchKind
  Defines the type of noarch that a package could be.
• PackageArchiveHash
  Package urls in explicit environments can have an optional hash that signifies a hash of the package archive. See ExplicitEnvironmentEntry::package_archive_hash.
• ParseBuildNumberSpecError
  Composition of possible errors when parsing the spec for build numbers
• ParseChannelError
  Error that can occur when parsing a channel.
• ParseExplicitEnvironmentSpecError
  An error that can occur when parsing an ExplicitEnvironmentSpec from a string
• ParseMatchSpecError
  The type of parse error that occurred when parsing match spec.
• ParsePackageArchiveHashError
  An error that can occur when parsing a PackageArchiveHash from a string
• ParseStrictness
  Defines how strict a parser should behave.
• ParseVersionErrorKind
  The type of parse error that occurred when parsing a version string.
• Platform
  A platform supported by Conda.
• RunExportKind
  Type of runtime export. See more info in the conda docs crate::package::RunExportsJson
• StringMatcher
  Match a given string either by exact match, glob or regex
• StringMatcherParseError
  Error when parsing StringMatcher
• VersionBumpError
  VersionBumpError is used to specify the type of error that occurred when bumping a version.
• VersionBumpType
  VersionBumpType is used to specify the type of bump to perform on a version.

Functions

• compute_package_url
  Computes the URL for a package.

Type Aliases

• BuildNumber
  Named type for the build number of a package instead of explicit u64 floating about the project.
• BuildNumberSpec
  Define match from OrdOperator and BuildNumber as Element
• PackageUrl
  An package identifier that can be used to identify packages across package ecosystems.
