Struct Requires 

pub struct Requires {
    pub os_min: Option<String>,
    pub glibc_min: Option<String>,
    pub libs: Option<Vec<String>>,
    pub bin: Vec<RequiredBin>,
}

What the host must already provide, by names the operating system defines, so a consumer can check before installing. Nothing here names another project or where to get it; see the specification’s Host requirements section.

Fields

os_min: Option<String>

Minimum OS version, in the OS’s own terms: 12 for macOS Monterey, 10.0.17763 for Windows.

glibc_min: Option<String>

Minimum glibc for a gnu Linux build, such as 2.31.

libs: Option<Vec<String>>

Shared libraries the executables load from the host, by the name the loader resolves: a soname (libssl.so.3), a DLL name (vcruntime140.dll), or a dylib name (libssl.3.dylib). Excludes the C runtime baseline that libc and glibc_min cover and any library the artifact ships itself. packslip create reads it from the executables; an empty list means they were read and need nothing, an absent one that nothing was checked.

bin: Vec<RequiredBin>

Commands the executables run and cannot work without, by the bare name on PATH, with an optional minimum version. Declared by the vendor.

Implementations

impl Requires

pub fn is_empty(&self) -> bool

pub fn summary(&self) -> String

One line for a report: os>=12; glibc>=2.31; libs libz.so.1; bin java>=17, with libs none for executables that were read and need nothing.

Trait Implementations

impl Clone for Requires

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Requires

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

Formats the value using the given formatter.

impl Default for Requires

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Requires

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Requires

impl JsonSchema for Requires

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Requires

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Requires

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
